I know this is probably a pipe dream, but I have been playing my fury warrior more is the last couple of weeks and I see one change that could be made to help rogues out in the burst department.
Expose Armor could be reworked to be more like Colossus Smash, where it gives us a personal arpen buff for 6-10 secs. That may h be making rogues and warriors too similar though, but it is just a thought of how to make us a little more bursty. Another thing, but again probably too similar to fury, is to give us something akin to recklessness, cold blood is good, but something that lasts for more than one attack would again give us some burst damage when encounters need it.
I haven't thought about pvp tho, I imagine a shadowdance/recklessness combo would be pretty deadly and not a likely change, but it's just some thoughts.
