Ya I swapped from stam sorc to magicka necropotence setup and it's pretty fun. It's not always the best DPS on groups unless its AE but I have ton of survivability and when retards die in lightning on molag kena hardmode (white gold tower) or lord dusk (imperial city prison) my pets usually end up tanking the boss (wut) and since they seem to never die I have plenty of time to ward+rez. I tried that stam sorc in VMA and it was yeah very fast paced and just pain in the butt getting around to each monster everywhere as melee ranged.
As for VMA, omagud, necropotence setup made it so easy rofl. I also just made a dual wield/2h nightblade for pvp but think I'm going to swap him to bow, being in melee range during zergs is just a death wish. It is fun for ganking but its hard as hell to get away, I try to cloak for invis but some dot always breaks it. Also gonna look into pvp sorc, leveling one of those too.
If you're risky like me, you can go to alkir desert and afk at one of the dolmens, use like a repeater key setup or what not and you can AFK to 50, lol. Buddy got a 72 hour suspension after doing it for a few weeks, I haven't been busted yet, but screw leveling alts the normal way. Takes lot of work after that though, spent like 5-6 zones getting mage guild books and skyshards for skill points.
