Precisely. I specifically mentioned Spencer because of how easy it is to Spell of Vishanti XFC his zip wire on reaction. Truth is he can kill just about every character in an easy way by XFCing SoV, but Spencer is the easiest I’ve stumbled upon thus far.
That wasn’t me. 
people say its dorm on my team but i know taskmaster is the problem back with beam assist iron man or doom can play both.
Vergil anchor shock with meter is the same as dark phoenix summon sword + devil trigger teleport = win
Everybody is a problem on my team.
But people say that Cap is my best character…
Felicia WILL be the problem on my team, I played her in MvC3 for a bit but I eventually dropped her. Now that’s she’s even better in UMvC3, I started practicing again:)
I guess if I had to label anyone on my team as a “problem” it would be Wright. I love him, but he relies way too much on assists while he’s in Investigation.
It’s definitely Wesker. In Vanilla Spencer was a decent problem as well, but I’m having some adjustment pains so far even though he’s been buffed. Different moves and zipline speeds and fall speeds for him have been messing with my head, but it shouldn’t take too long before he becomes a problem again.
Hm im running so many teams at the moment. But mostly with either Dante, Vergil at least in them. They are both problems for my opponents apparently, it all depends if I input everything correctly with Dante too lol. I think Dante is my best character by far (Mained since day 1) but people said they were afraid of my Vergil, and when I have Wesker on my team (I actually like the character! but I only use him in srs fights, I don’t wanna use his cheapness lol) They think he’s the problem even more. But Dante gets the most consistent kills I’d say with Wesker if I use him. Unfortunately they are probably both the same level lol. So I guess…all? lol
But probably Dante due to me knowing him so well now. Hawkeye, Spencer, even Doom anchors are doing well lately too
All of my characters are problems now and I love Ultimate for it. In vanilla I built my team entirely around Zero. Dante and Sentinel were perfectly capable as characters but I wasn’t any good with them. Zero did all the work backed by Sentinel assist then Dante came in to finish the combo video.
Now though I still have a team (two teams actually) built around Zero and all of the characters are capable of OCV’ing a team while still having optimized assist support for Zero. I also gotta say that as much as I miss DHC’ing into Devil Trigger for full-retard combos, having Proton Cannon to DHC to and still get big damage is a very relaxing break.
Spencer is definitely my problem character. He’s just too good of an anchor but my Chris can cause some serious problems if he can act on an incoming character, especially if they don’t know about push-blocking. Chipchipchipchipchip.
Nemesis, he’s gross.
Jill on my team of Jill/Deadpool/Trish. But this is mainly due to the fact that I have issues doing her combos online. I frequently miss her jump cancel combos that I usually don’t miss offline.
I have another zoning team of Deadpool, Arthur, and Trish. Even with his buffs, I still have issues with Arthur. His daggar assist is great, but peakaboo just isn’t enough to get people off him.
Trooooonnnnnnnn- nope.
RIP Tron & She Hulk.
For the team using ATM it’s Nova. He can lock opponents down with javelins/hawkeye assist, setup duriable reflectors, and setup combos off throws. He really positions my X23 well enough to kill whatever is left with a serviceable assist.
I Don’t know depends on matchup,
When I run Zero, Vergil, Strider. Zero is so annoying, So patient slowly eating away at your team, then I bring in Vergil with meter and he’s bullshit. Then I come in with strider with X-factor or orbs and he’s been an annoying assist the whole match too.
When I run doom though, that guys usually the problem, so frequently 1 touch death.
Depends. If I can get Frank to Level 3 or higher, they are usually screwed. Otherwise, Taskmaster can be a pain in the ass with his versatility and all.
Zero
Hawkeye
Doctor Victor Von (fucking) Doom (w/ Hidden Missiles, no less.)
They’re ALL a problem.
Phoenix… on point. And X-23, when that fails.
Frank West if I screw up and somehow leave him at Level 1. However, I’ve still tapped dat Voluptuous ass with level 1 frank by just being smart. (ZOMBIE THROW LIGHT BABY!)
Although I’m generalizing…
X-23 against inexperienced players.
Doom against the rest.
I think overall, my Doom is scarier. Already wrecked shit in Vanilla with him, now I don’t even have to try anymore.
