Call me a noob, but I currently don't use quick strike much. I plan on it, when I buy the extra weapon slots, but as of now I use hide, sneaky attack, and then rend, and tough the rest out with normal attacks. By the time rend has cooled down, I will be dealing the final blow to most of the lower level zombies and skeletons in the catacombs. I can do this two or three times before I have to find a safe spot and heal up, and then it's a matter of wash, rinse, repeat.Show me a rogue that doesn't use quick strike...I think I've grown tired of this subject in it's entirety...
I think SA is fine right now, maybe due for a slight increase in damage, but no real complaints.
I just think people need to really start using quick strike more. I've found that QS does more than enough to offset the reduced damage of SA.
I just think people need to really start using their brains more. I've found that brainpower does more than enough to offset the glib arrogance of beta testers.
I'll use poison weapon and quick reflexes just before I go in for a sneaky attack, and then switch the skills on my hotbar quickly. It's not the most efficient method, but it works.
As for sneaky attack, it works fine for me. I'm already doing damage comparable to a giant swing from my warrior, who is 44 at the moment (my rogue is 29), and while this may not be as powerful as the nuke damage that you're talking about, it is powerful enough in my opinion. I don't see why it has to be changed at all.
