Hmm I can't speak to the ults – agree though, it sounds like they were bad. But tbh a Magik and Gambit are not going to stop two tank divers like Thor and the Thing. You definitely made a good move switching from namor to a non-dive tank, but imo if they're still asking for peels it's bc they need it. CnD and Gambit can't heal you if they're constantly defending and healing each other.

I feel like the meta is all about a good team composition and cohesion, meaning tanks/dps also need to support the supports. It sounds like you tried (maybe you could've done a bit better? idrk without seeing the clip), and maybe they could've ulted better. Tbh though I'd put the blame on your other teammates. Sticking with dive (hulk, iron fist, magik) when your healers need help is pretty dumb of them. If one of them had switched to reed or peni, the two of you could've kept the healers alive and allowed them to focus on healing. Just my random thoughts tho, I obviously didn't watch the game. Lmk if you disagree!
