Keep attack pressed for automatic attacks

In easy fights - when ennemies are too weak to bother - sometimes i'd like to speed up the process. Especially when you have to tap and tap and tap again on the same button.

I thought about this: if you keep pressing down on the attack button, the character would automatically attack every half-second or so, until you release the button.

If it simplifies the game too much, you could imagine having this being unlocked after some "brawl mastery" level is achieved wr after a quest or something.
