It's at least around 10% dps boost to rotation alone, not counting boost to jumps. And about a 5% loss vs old rotation if you ignore positionals. If my math is in the ballpark at least * not an expert at these things *
Yeah, and it's nothing you didn't already have at 56 before you get Wheeling Thrust.

I'm talking about specifically what you gain at 58, which is nothing except more complication.
