I don't have time to explain all the reasons you are stupid.
Aren't rogues supposed to be single-target damage dealers? Blizzards attempt to give us do AoE attacks isn't fun, or useful. Fan of Knives... it looks cool, but the only way I can see this being used is by spamming it in WSG when multiple people are capping the flag, just to disrupt them... I may be wrong, but thats all I find useful for it.
Another thing I want to point out is Killing Spree.. attacking every target within the range, that isn't effective in PvP, maybe in PvE in some situations, but not many. I think Killing Spree would be better off if it attacks one target. If your trying to kill a hunter or warlock, you don't care if you damage the pet. Anyone else think Blizzard should stop giving us AoE attacks? In my opinion they should change killing spree and make it attack 1 target, or give it an option to attack 1 target with some kind of a glyph and increase damage per hit.
