Duh. Um, she’s a TOP TIER ASSIST. 
A cheap win against dumb scrubby stuff, sure. A cheap win against good players, no. She is a top tier assist. Get used to it. Counter her if you need to.
pot kettle black
Reread. I said “dumb stuff”. You running into Tron == dumb. Losing your block is also always going to be a problem in any game, so yeah, that’s dumb too. She does very little chip damage and very limited range… your options are clear.
Well, yeah, duh, those are great teams. Don’t get confused. You need to remember that much like Psylocke, who you wouldn’t run into, Tron is actually “good” and “useful”. Since all she can do is punish you if you run into her, um, yeah, that’s actually incredibly limited. And it looks like you already know the countertactics, according to you.
If that’s the worst ‘total bullshit’ you have to deal with in Marvel, you play against utter scrubs and should never lose a match again.
Your problem begins here. Snap her in. You can’t land a snapback, that’s your problem.
This is a scrubby thread so far. Stop typing, and for the next two days just read what everybody said before you go off to play Marvel. Guile/Tron and Cammy/Tron are EXTREMELY good “low tier” teams.
Come on, guy, this is scrubbarific. Of course Tron is good enough that people keep picking her. If it wasn’t her for your opponent it’d be Psylocke (much more annoying), Doom, CapCom, Cyke, Juggy, Sent, blah blah blah boring blah. Consider yourself lucky that they’re that bad and move on. This is a dumb thread. Marvel’s got tons of glitches or accidents that change the game far worse than anything Tron has. Counter them with Omega Red (poke-age) or Dhalsim (teleport) or Cyke-AA or Ken-AA and see how they feel then… if you really need to make the bad people stop picking Tron. Hell, even a good Akuma-expansion team can beat up Tron pretty easily. You’ve said they suck with Tron, so get one of the snapback-friendly teams and use that. =P
