Dunno man, i don't feel powerful at all, at least in my guild.
here's our logs:

To me it seems like classes that are WAY easier to play have way more output and way more use in all the fights.
If you compare us to rogues, they do MORE damage AND they got smoke.
As for the fights themselves, there are many targets that need to be nuked down. so i barely even get to use my clones or AoE.
At least not on the first kills.
I'm sure for padding the meters we can do better.
but all-in-all, monks are kinda crap.
