Agree, definitely a game changer and in my opinion one of the best changes we've seen through EA.
It's even weirder to think that at some point there were users on this very same forum arguing AGAINST its addition.
I have only been browsing the forums for a couple weeks now, so I completely missed this discussion when it was relevant, but the only counter argument I can think of is that some players might not be amused having their combat slowed down by constant interruptions. But the interruptions can be toggled on and off, so even those players should be satisfied. It's a win-win situation, I wish this approach of letting the players choose how they interact with the systems was more common and applied to some of the more controversial decisions Larian made.
