Im a combat rogue and i use clicking but my dps score is lower than i want and i wish it to be better. I heard hotkeys are much more useful than clicking. Im a lvl 75 combat rogue. If anyone gives me a useful list of hotkeys i will award 10 points. thank you please help im tired of getting called out in dungeons.
Thank you those that have answered so far but I want a list of moves and the key i should assign them to

I got to say I disagree with Nick, not everything has to be hotkeyed. i reckon, per class there is roughly 30-40 abilities and functions that need to be binded, personally I play Hunter, so I have alot of macro's relating to pet abilities. I have my usualy 1 - = bar and then F1 - F12 as well as a WoW gaming mouse with all buttoms bound, I have no problems with this set-up

Z b
Ctrl 1 2 3 4

And so on
Use the keys you can reach

All of your stuff should be keybinded. Don't click. You'll thank me later. Put what you use most close to move keys. Use esdf for move keys. Download bartender4
