Actually you aren't the first to suggest this being something applied to PVE content.

I think the reason this wasn't applied outside PVP is because some classes don't have the same sort of 1-2-3 combos, so their hotbars going from PVE to PVP content were consolidated and cut differently and that the PVP versions ignore procs.



I don't think it would hurt anyone to make it an option, though.
