From what I understand, Snake players are absolutely dominating the competitive scene right now. Apparently, Snake is considered top-tier.
I sadly have to agree: most of his moves can kill, he has some quick moves, his recovery is phenomenal (with SA to boot) and he weighs a goddamn TON.
I think Snake probably should've had less vertical recovery or weighted less. Thanks to his SA on recovery, he's basically impossible to spike and can survive hits during recovery which would gimp the recovery of most characters.
Sakurai gave Snake a bit too many advantages, IMHO.
