meanwhile I think thief is pretty good. I'm getting solid results before the skill coefficient overhaul, bursting wasn't much more dps than just autoattacking. but now, all coefficients got cut, but thief's initiative skills didn't. so relatively they got way stronger. so you can actually burst when you have initiative. if you still don't feel like you have enough damage, maybe you aren't building for it. Critical Strikes is big damage if you haven't tried it
