I would certainly not object to the affected skills getting tweaked like the Mudra inputs were.

The Bio thing is noticeable but manageable, I always assumed it was lag but I guess it could be waiting to register. I suppose it bothers me less as nobody ever died from me waiting a fraction of a second longer to Bane.
You are right, and it is a high hindrance to PvP, because burst damage is too fast.
