One thing that weirds me out a bit in that thread is that people claim you need to spend bunch of hours in training or know lot of framedata if you don't want to get blown up online. I've been doing just fine with having done combo execution in training and knowing if something I do is safe or not.
I've harped on this a lot but there's no way to communicate the vast gulf between the various skill levels. For some people being "good" means you're better than the average online player. For others it means you know how to do special moves.
SFV is easier but the gameplay changes mostly shrink the gap between intermediate and expert players. A 3f buffer doesn't mean shit to a guy who can't special cancel moves whereas for someone like me it means I can complete every Trial where in SF4 I had no hope of ever accomplishing that.
Conversely, the autocombo addition in MvCI will shrink the gap between an absolute beginner and a novice. No one would call a guy who could chain buttons into launcher into air buttons into super "good" but it's that guy who's going to get pissed at Capcom for dumbing down the game when he loses to an autocombo. No good player will sweat that.
