I think modern controls is here to stay. I messed around with it and damn is it useful for a lot of characters. For some, you prob shouldn't bother like most charge characters. For Ryu as an example, I can bust out a hadouken or shoryuken at will using classic controls, but when it comes to big combos ending with super, im just not there. Modern just helps with that. Mix that in with you don't HAVE to use the modern controls for special moves (you don't get the damage nerf if you do it the classic way) and you got yourself a really good system for some. I don't know if i'm going to keep playing modern, but damn if it isn't tempting.
