Magblades have gone through a lot of changes. They’re pretty kickass now. I helped a friend build one a purple of months ago...PvP and PvE they hit HARD. Some tips to get you started:

Alcasthq.com is a good place to start. His builds are very good, he explains them well, and he always includes a gear setup that is easy to acquire and a half CP allocation. When in doubt, follow his build then adjust from there.

Your race is fine. Altmer is still a top performer. Vamp should be fine.

Radiant magelight can be exchanged for inner light. The max magic boost will help you more than the increased radius. As a magblade you don’t need to hunt as vigorously.

Harness Magicka is a more important skill now. The magic return helps a lot.

Siphoning attacks is very important now. The game is heavy on resource management - anything you can do to get magic coming in is very valuable.

I like a double Destro setup. A magblade doesn’t really need a resto staff’s heals.

With double Destro you can go soul harvest / destro ultimate. This will turn you into a ultimate proccing machine of insane proportions.

Your gear sucks. I don’t think you need to think vampire on your gear at all...class abilities do more to overcome issues there. To get back in the swing of it, id recommend julianos as the base. Make the weapons julianos. Then you can do 4-5 pieces of a magic drop set, then 1-2 monster helm. The second set doesn’t matter that much, especially if you’re doing 4 pieces. Just something that offers slightly better buffs...necropotence, mothers sorrow. If doing a 2 piece monster set, grothdarr and valkyn are brutal. Illambris can work with some thought to skills chosen (to get fire and lightning damage).

Gold weapons are very helpful. Gear can be purple until you love the build and need the marginal boost for gold. Right now the “meta” is nirnoned on your attack weapon and infused on the back. This is pretty good, for complicated reasons I won’t explain here. If you plan to PvP, impen is VERY important right now. You might need two sets of julianos if you’re going to PvP and PvE.

You’ll suffer a little for the lower CPs, but the game is so frontloaded in the cp tree now that you will pull about 80% the power a max cp character can. So it’s not a deal killer. For the most part, I agree with alcast’s 300 magblade PvE allocation. However, he is focused on trials and vet content. So I’d make a few tweaks. In blue I’d reduce thaumaturge by half and forget staff expert. I’d push these into element expert and elfborn (I do less DOTs than he does). In reds, I’d reduced thick skin and stick more w Hardy and element defend (you get hit with less DOTs when yo don’t play heavy trials). In green, I might reduce tenacity a bit. You’re working toward 75 in arcanist. I also like some in stamina and health recover...I know he doesn’t, but I play more diversely and don’t need to max.

Hope that helps. You have a potential dps monster there...he just needs some tweaks to catch up w the game changes made over the last year.

I can only say with certainty that it sucks because I’ve been there. 12-18 month’s ago, and my magblade was in all the trendy vamp gear because I though he needed it (and he’s really into Twilight, as any Breton magblade probably is).

But with changes to the game, CPs help overcome a lot of vamp downsides, and their class abilities help overcome others. I learned to soul suck while using harness magic. Healing behind that shield will make it feel like you have zero health regen handicaps at all.
