Most of us rerolled sniper, yes. At least, in my experience. Lethality and Marksman have better in-tree synergy than Madness and Lightning, all three tress offer distinct playstyles and all three trees are actually worth speccing 31 points into. Cover is a buggy hindrance, but the class still feels more fleshed out than sorc.
Even at it's peak, Sorc always felt like a half finished class. It was like the devs had this really cool vision for it in their heads but could never fully realize it or get it to work. Like, halfway through designing the class, someone panicked and said "This isn't going to work, change everything" but they didn't have enough time to do that, so they just tried to force what they already had done to fit the new vision. The result ended up being the directionless class that we're stuck with today.
