Just read through that thread,
Some old BT elitist spent most of the pages arguing that all deviation from BT turns the game into a twitchfest.
I wonder if he's actually ever tried playing MWLL. I hope he does and spends a little while extracting foot out of this mouth.
MWLL is about consistency in aiming and accuracy, maneuvering well and situational awareness. Twitch skills don't come into it in the slightest, even lasers require consistent aiming.
His closed minded opinion really does worry me.
