After discussing the matter with Northern Polarity for too long (almost five minutes), I have come around to the group thinking 4* Thor and Wolverine make everyone in PVP irrelevant. There were several levels to this discussion.
First, the 3* tier is mostly balanced. If the 4* were banned from PVP tomorrow, you would see greater diversity than prior to the the introduction of Fury and buff of X-Force. I belive not facing/using the same combo over and over would be good. What does this mean? This means that X-Force and 4or do exist; and therefore, all 3* don’t matter and there is not diversity. If a player has X-Force and/or 4or at usable (sometimes unusable) levels, those are the characters the players will use regardless of their 3*'s.
Second, because players will use X-Force/4or no matter what, the featured character does not matter. This defeats the purpose of each character having their own PVP. The featured character should be the one that the team is built around and not just there to take up space.
Third, if 4or and X-Force make all other characters irrelevant and if this irrelevance is concluded to be bad, then 4or and X-Force should be balanced.
Discussing with J and NP, X-Force seems pretty easy to balance. NP felt that just make SS not gain the player AP and it would be balanced. I felt in addition to that, the green ability should cost 10 AP and black 13 AP (or 2 more AP than they cost now). To me, the reason X-Force is so dominant in PVP is his speed. His green and black are so good, players do not even bother thinking about a non-3 yellow cover build because the battles are so fast. I believe slowing X-Force down, but keeping the damage the same (without the AP gain from SS), would make him powerful, but closer to being balanced with other characters.
However, in exchange for this, I would also tweak his yellow so players would also be tempted to get more yellow covers. Either a Patck constant regeneration, or A Wolvie regeneration with every yellow match (without the below 50% stipulation). At worst make the count down go down to 1 with 5 covers. If X-Force is going to be slower, he needs a regeneration that actually works better than a lottery.
4or was a little tougher. NP felt that 4or’s health was too high, I felt it’s 4or and should have higher health along the lines of the difference between the 2* and 3* version. I did not think health was the problem. I thought the problem was the combination of speed and health. The other thors have relatively high health, but are slower. I felt her blue ability was all that needed to be tweaked. NP disappeared (IIRC, which I probably do not), so he’ll have to pop on here to tell you his thoughts.
I think there are two options to tweak blue. One would be less charged tiles (not sure how much less, I do not do math). The other would be to tweak the stun. There are a lot of options here: (1) make the stun only 1 turn, (2) remove the stun, (3) stun 4or 1 or more turns to prevent smite right afterwards, or (4) stun the player’s team for one turn. The last one would create the charged tiles, but the AI would get the first chance to match the tiles. Since the primary way to balance 4or would be to slow her down, I would think blue needs to make less charged tiles. I would keep the number of charged tiles for each blue cover now, but have the 5th cover be the one that has the stun and the 5th would not increase the number of charged tiles. Given this option, I am not sure how many turns the stun would be, or if the stun would just be like Venom and stun the AI team for one turn. There are lots of choices, but without the number of charged tiles increasing for the 5th blue cover, 4or should be more balanced with other characters.
I’m not really worried about it. As others have posted many times, the list of OP characters that eventually get balanced has been established. I do not see what the fuss is. We all know eventually they will be balanced, and we all know it will not be any time soon.
