But what's the major difference between AP just simply GIVING you something like a Heaviest Shot with 200p while at 4 stacks of Repertoire and having AP rewarding your procs with a Heaviest Shot with 200p?
Because it changes the way the song interacts with crit, and I see that as a positive end in and of itself.

I'm curious, do you think I'm the OP whom suggested the Velocity Shot thing?
No, but what you're asking for is just another WM and MB with different lipstick. Just because you don't press an oGCD button doesn't make it different enough imo to justify the button / complexity bloat associated with having three songs. I like the goalpost design of AP, it's kinda just as simple as that. I wish it were sexier, but I don't want a significant rework.
