PvP question with newly leveled roster
Ok, so I recently leveled up seven of my characters to 166 (Grocket, Cage, Cyclops, Blade, Doom, Hulk, Deadpool) after sitting on tons of iso for quite a while. All of my other characters are lvl 110. On the RedEye PvP tournament I ran 4* Cyclops (base character since I only have 1 cover myself), Grocket(boosted) and Doom (lvl 166). I had few problems beating teams up until around the 700 point mark and I was sitting on a horde of health packs but didn't have to use too many since Grocket could usually heal to full and only had to periodically use them on Doom. I finished the event with around 830 pts. and ranked 2 in the event. I noticed though at the end I ran into a ton of Iron Fist/Hulkbuster maxed level teams. I skipped them as I knew I wouldn't be able to match that firepower but eventually they were the only teams that kept coming up. This prevented me from getting to the 1000 point progression as I didn't want to spend all of my health packs trying to take this combo on. Is this all the top tier of PvP is now, dominated by this team combo? I imagine there isn't much chance to combat it without a developed 4* roster?
