Instead of having to do the extra punch when they're on the ground, just gets a bit boringly formulaic after a while. Much rather a more streamline heavy punch on the fly to be responsible for a knock out, if that gets boring, at least it's less. One could also make a mod so all knock outs are civilianly easy, but I don't mind the quick time, I just wish the end of my effort there sealed the deal, more satisfying after a little back and forth.
You could even have it be more difficult for higher ranks, oh this mechanic was so wasted on IO interactive, the things they could've done, like multiple opponents to make it like a dual takedown improvised or even grab a glass on a table what a waste. But that's just me. Anyway, thanks for reading.
