I have no issue with trick attack honestly. It's rare that I miss the buff honestly and it is frustrating but I like it as it is.

The real handicap with ninja is the mudra lag. It prevents the class form being played as intended and can significantly drop dps if it is substantial enough. The mudras need to be client side but I honestly don't think the developers care enough about the issue to fix it which is kind of sad because ninja is my favorite class.
