I have been running an imperial stamina sorc since launch and although the dps is lower than my nightblade it makes up for it in survivability. In 1.6, the dps is so much lower than my nightblade (and the survivability is also much worse than it was) that there is no longer any reason to play my sorcerer. There needs to be some serious buffs to stamina sorcerers, at the moment all of their passives have to do with things like spell damage and spell crit but I thought this game was about playing how you want to play. Can't really say that when a class has only boosts to magicka and nothing to compliment stamina at all. The removal of weapon critical from the dark magic tree is just a kick in the teeth.
There is no reason that a class should be this bad, the magicka sorcerers have just had some minor buffs announced that should reduce the gap between sorcerers and other classes however nothing has been done for stamina sorcs at all. If they stay this way in 1.6 I'm going to have to shelf my favourite toon just because ZOS nerfs an already balanced class/spec and wont offer race changes so people in the same boat can change to a race that better supports magicka seeing as though that is the thing to do now.
