Please consider adding this either by default (Large games like Overwatch do this) or as an option.
Specifically, I have tendonitis in my elbow (“Tennis” and “Golfer’s”), so constantly clicking or pressing the same buttons is just additional stress to carry out the same intent I have (Continue attacking)
Additionally, it might be worth considering that attempting to balance around a player’s “ability” to spam a button opens the game up to macros being more of a “balance issue” than if the game simply performed the actions at the intended rate.
