It's always been my impression that if you pour skill points into each and every crafting line on a particular character, that you might be sacrificing your ability to max out your class, weapon and armor abilities, as well as the guild, alliance and world lines. I'm wondering if anyone has attempted this, and regretted it later. I know you can always respec, but that leads to a second question - what happens if you max out crafting and then respec, and take skill points out of crafting and redistribute them elsewhere? Do you then lose the ability to craft high level items?
Speaking as an Altaholic (waits for everyone to say "Hi Duiwel")
I can for certainty say you will not max out the skill points for most crafts on your alts, unless you are really dedicated towards it, you will also not max out all ability skill trees (at least not initially).
Here's what I recommend:
All 3 class skill lines, choose 2 weapon skill lines, with a third option (slightly).
Say you are Magicka:
Destro staff, resto staff, dual wield for example.
For Stamina:
2h, Dual Wield, bow.
You can pick the essential guild skills, alliance skills, such as Rapid Maneuver ect.
For the crafting I recommend the blacksmithing, clothing, enchanting as a primary priority & provisioning and woodworking are secondary.
Note it will take a long time to get all the skyshards, random dungeons & the Alliance war rank skill points on multiple toons
Alternatively you can decide to use 4 chars as your "main ones" 1 of each class & then have the other 4 as primary crafter characters for the mails, while you get their skill points for the actual skills. This is another option I am currently experimenting with on 2 of my alts.
While taking skills take a long time, doing Undaunted on them will be even more tedious so be prepared OP
