Sometimes you have to wait a split second to make sure the mudra went through okay...but then, that's mudra lag :P with me the lag can vary wildly, sometimes it's perfect and I feel like changing mains, sometimes it's dreadful and I want to crawl into a hole after refunding all the gear I got for it.

Ninja damage is NOT low, maybe compared to the other 2 melees but you're definitely on their heels - not to mention Trick Attack is a raid-wide dps boost. That said their aoe is awful.
