Bard. What if Straight Shot "proc" was not rng?

And if it ends up being a buff, it's just a matter of tweaking potencies to compensate for it.

I don't think you'd want that the same way MCH probably wouldn't want to lose their procs. On the assumption that the ability is overbuffed to compensate for it's proc nature, the potency decrease and removal of gameplay fluff probably would not feel well. I mean I don't think you'd enjoy it so much if it only hits marginally higher than a straighter shot.
