Alright I guess I would be considered one of those "hardcore players" since I have put in about 3 Days worth of time so far. Don't judge I'm on terminal leave haha! If you can log in once a day even as a family man that is a plus for sure(even for 10 minutes for research sakes!). SO you CAN do all 3, and off the bat they will be viable, for your first 20 levels or so. Start your planning now for once you reach level 50 and beyond.

To tell you the truth my BS and Enchanting is past my current character level of 42. I can make level 50 gear however I get questing items too quickly that are just better that what I can make for the cost. I just deconstruct EVERYTHING and store the items on pack mule toons for later use. The trick to making viable armor is using the crafting stations spread around the world for the armor set bonuses. Along with knowing traits for the items you want to craft. Now this where they go hand in hand. All of these crafting stations require not only the materials to make the armor and weapons, but a certain number of traits in each piece. So for example I'm currently in The Rift, and I stumbled upon a crafting station with a rather nice set bonus. The downfall to creating that set was I needed to know 6 traits on a piece of gear in order to craft it. So you may think well 6 traits how long can that take, quite some time actually(I'm guessing but like a week or 5 days worth of total research PER armor or weapon piece, from 0 traits to 6 traits). And since you can only research two abilities (as far as I know for now, because I have only have 2/3 points into research) you will have to pick and choose wisely. At the end of the day it all scales down to time, rather than skill points. Early on it may seem daunting with skill points, but you don't really need to invest many points into the professions because I personally have not crafted any gear since level 20. Once you get to a higher level, you will have plenty of skill points if you quest and find skyshards.

So I danced around a little bit, but keep an eye out during questing for ANY items(white/green and even blue) with traits that you don't have researched. And ALWAYS have your maximum research going on for all professions(WW/BS/Cloth). Since you are a family man this will require some planning and holding onto extra items for those days you can only log in to "check your mail" so to speak. On the days you play extra and collect items from adventuring and questing, hold onto those items for research later. I have a little notepad open and have marked down what I have researched so I can use it for quick reference without having to run back and forth to the forge. Even though I'm not a woodworker/clothier I have invested skillpoints into the research ability so I can research two things with those as well. Am I a crafter of those professions right now, no, but if I decide down the road with some spare skill points(or Re-spec) that I want to be a woodworker, the research is done and I can begin crafting viable gear for myself and for profit.

Now I know I said earlier that I get questing items that are "better", and some dude might quote me and say "well actually, blah blah blah" and he will be right. I can craft better stuff than I get from quests however it is going to cost me a lot in upgrading materials which are very valuable right now. I deconstruct EVERYTHING and so far I have around 60-70 honing stones(green), 30 Dwarven oils(blue), 2 of the BS purple upgrades(dont remember their name), and 1 of the legendary upgrade items. That stuff is most likely going to be much more valuable later on creating a piece of gear that I will use for days/weeks, or using to craft set items for someone to buy. Because right now I could make a nice Blue chest plate and go the whole 9 yards, and it would be great for 2-3 levels, but then I will get a green chest plate from a quest 9 hours later that would replace it and I don't think those materials were worth 9 hours of use.

That's all I can think of for now, it is a lot and pretty jumbled but should help with your planning. Which is what everything in crafting comes down to because it takes TIME.

First, what @Mattir said was pretty spot on, in my opinion. If you're concerned about time investment, my advise would be to forget about enchanting altogether for now, and do clothing and blacksmithing.

There is ongoing debate whether or not enchanting is so slow to level by design or if it's bugged... but regardless, in its current state it's an extremely frustrating and unsatisfying slog. I wouldn't drop more than one skill point into enchanting until you're damn sure you really enjoy it (for reasons that escape me haha).

Blacksmithing and clothing are much more satisfying in my opinion, and I do both on my assassination nightblade as well. As far as focus between those two, there's probably two schools of thought. One - you have more armor slots than weapon slots, so clothing may benefit you more in that respect. Two - you can focus your weapon research easier on just one weapon of choice, so you can get your ideal traited weapon. I'm in agreement though, go ahead and pursue both simultaneously. There are more than enough skyshards out there to provide quick skill ups... especially if you turn to the dark side and look up a skyshard location map (neither endorsing nor discouraging this action!).

Oh I definitely plan on focusing on two crafts....I just can't decide which two of the three I listed. I guess I always assumed I was going to stick with enchanting, but you raise some interest points.

hypothetically speaking....if I stuck with enchanting....which should I then focus on clothier or blacksmithing?

--edit--
But I am seriously considering going with blacksmiting and clothier...hmmm. DAMN I CAN'T DECIDE. I know I want to focus on two crafts and sink a few skill points into it from time to time.

I am building a dual blade assassin as well. And I am planning on only putting points into two crafts pretty much the same way you do...except maybe a hireling or two. And I won't try to craft whole sets of gear every two levels...the two crafts I eventually pick will be leveling as I level so that eventually at the end I can craft whatever gear I may need as a high level assassin in whatever end game there is. Does that make sense?

Anyway, I just figured focusing on two crafts while questing and leveling and whatever else would be the most feasible. But my philosophy is the same as yours....I want to craft things and enchant them for myself. Unless I choose clothier and smithing...in which case I will just craft things for myself.

God...maybe I SHOULD just focus on three crafts....there ARE a lot of sky shards......
