I've played around with rogue and sorc so far. The two do feel different to one another, but within them - feels like you have "defensive melee sorc" and "squishy sorc" and both play almost identically. Rogue is either melee zip zap or mid range zip zap. Both play heavily around maintaining cc.

It feels like there's a whole skill slot missing. Or some skills/passives need a bigger buff to allow for more utility options. Basic skills being kinda meaningless, you can either have one to press to feel like you are doing something or you run around for 2 seconds not pressing anything if you take an actual skill instead.
Like sure, you can take combo points and auto attack three times... Which feels bad because the skill itself does basically nothing.
