Simply put, f--k what he said. It's a shit attitude that hurts the genre.
Nothing against him personally, but that attitude and the people who believe it- they hurt the genre.
I guarantee execution will still matter heavily in high level SFV.
Look at HDR. Sirlin simplified inputs in that. Execution still mattered. (don't say it didn't)
Look at KOF98. Simple inputs- execution matters.
VF5FS. Some simple input stuff is very high execution. (there are a few things on a couple of characters needlessly complex in VF)
Look at Damn Skullgirls- Mike Z intentionally designed inputs to be as easy as possible, and that game is VERY technical.
The only thing intentionally hard characters is often take cool characters and make them inaccessible for average players- and reduce character diversity. That wasn't a big problem in SFIV due to 40+ chars, but it would be a bigass problem in SFV.
I'll gladly sacrifice James Chen for more newer players sticking with it, and ultimately, James Chen types aren't going to do anything other than grumble- they're not going to quit.
I really hope Capcom sticks to its guns on this- I bet doing things this way is going to lead to more people sticking with it, and learning actual fundamentals instead of what we got with SFIV, which was just unfun to play against.
