Initial thoughts on yondu buff.
Definitely an improvement in terms of damage. Love the utility that was added. But just feels like it needs more.
I'd make the precision off the l3 permenant. With a max stack of 1. I would also change the % to trigger a bleed/armor break to 60% on base then incorporate a increase/decrease of chance depending on class relations.(20% increase with advantage)(20% decrease with disadvantage)
Then add a taunt or infuriate on the heavy attack lasting 12 seconds. Also reduce the combat power rate reduction to -30% just feel like -50% extends the ramp up for l2 by a large margin.
