On the grapplers thing, imo, the 50/50 game once they get in isn't the problem, that's how it is in every game, when a grappler get in on you, you pay the price. Problem is, in good games you feel in control during neutral, if a grappler manage to open you up, it's either through a sick read or you fucking up. In SFV there's way too much randomness in the neutral, someone just jumping in and pressing different buttons with different timing would manage to get in on a lot of characters, then there's the yolo armored moves in neutral, CCs, etc... Even Alex would have been great if his vortex was better, it's not like he lacks yolo approaches, the payout is what he lacks.
Basically, grapplers are awful to fight because there's too much guessing in the neutral(which end up making the whole match feel random), not because of their vortexes.
