I'm not talking about button mashing like how some of us get through God of War or Tekken. I'mnot talking about normal, one-press QTES.
I'm talking about button mashing like the one found in Vanquish which is required to beat bosses and the ones found in other games like RE6. Button mashing is terrible because
1) It interrupts flow so badly
2) It's uncomfortable to the player especially when a heavy amount of it is needed
3) It doesn't feel intuitive and is just in place for completing a mundane task (opening a door by mashing R2? Sigh...)
4) There's never a button that is actually good for this button mashing. They barely pop out a few millimeters out of a controller, why did this idea even come to?
And many other reasons. On a keyboard, it may be more acceptable, but it's annoying nonetheless. Button mashing being mandatory is a dumb system that should not be in 2012 especially on consoles where it's most uncomfortable.
