I don't want "top tier" predictions. I want "bottom tier unplayable" predictions! It's more fun to put people on blast for that later.
Chris and Ryu. You can put me on blast if any of these end up being top tier.
I don't know where the big bodies stand. I thought they would be OK in this game but after seeing damage potential and the way armor works... big bodies look like they might really struggle in this game but for different reasons than in Marvel 3... they seem like they can get rushed down easier by just characters doing box dash jump heavies and then get hit for equivalent damage. They don't have an insane amount of HP advantage or a damage advantage, nor is their defense that potent. Like I don't know why anyone would want to play a Hulk over Captain Marvel when Captain Marvel can just turn on Photon Absorber (though in reality, Captain Marvel shouldn't have a function like that to begin with).
Though if you count Thanos and Thor as big bodies... they are going to be fine. May not be the best characters but they should be good enough. I am mostly talking about Haggar, Hulk and Nemesis here.

Soul isn't the worst for sure.
The Soul Surge ability is one of the strongest in the game. It has a far range, good damage and heal also pretty safe. But more importantly it has enough hit stun where you can tag and get a combo from it. That's what makes it deadly, it's like giving everyone a Ghost Rider like poke that converts into damage. The healing is also quite significant.
The Soul Storm isn't that great when it's active but the potential double resurrection makes it powerful enough by itself. The resurrection combined with the Surge makes this a very powerful stone for high level play especially for teams that just want to play it slower.
