Just tried a fight with Carol, IF and Daken. Against Chavez, Loki and Hawkeye. They are deadly I tell you. The board shakes and fills with crits and Hawkeye CD:s. And I had FOUR Carol black CD:s out. Had I only had some yellow I could have fixed it, but oh no. Bummer!
...I was able to use so many characters and so many teams that health packs were almost nil.
I kind of miss the old 1/2/3 version of Combined Arms. Juggernaut, Black Widow, and Luke Cage made a great team that the AI couldn't really screw up on defense: rainbow coverage with a single active on each colour.
