Personally I don't have a problem with one-frame links, as long as they don't dominate the meta-game. However, for SFIV they created too big a barrier in order to get to that pro-level, because of one thing and one thing only: terrible online netcode.
Most people playing probably don't get a chance to go out to Socal or EVO. I know casuals don't. So it's insane to put so many one-frame link combos in a game requiring perfect timing and zero lag, but then knowing most people play online, and knowing your online netcode is pretty pathetic. That's an arbitrary barrier being put up where there need be none.
So Capcom/Sony, please get good netcode this time. Don't use that as an excuse to overload on one-frame links, but at least in that case I won't feel the urge to travel cross-country in order to execute them consistently in a real match.
Why would anyone think FAs will be part of SF5? Every SF mainline game has had its own sub system apart from past SF games.
Yeah they're definitely not in there. On the other hand, you can use V-trigger like a FADC, so there's compensation.
Street Fighter x Minecraft
Not gonna lie, that would actually be a really awesome spinoff. A just-for-fun SF with that visual style I mean.
