I know its random, but its killing my that the last 5-6 single star cards (including the ones from the villain lightning rounds) I have gotten are the basic Iron Man and Storm classic, both of which I have maxed the powers for, and both 2 stars I have gotten were modern hawkeye. Here’s hoping I am due for a turn around…
Cad
Use them to create asecond of each character. 
Not sure I’d do that with the cost of cover spaces going up…
This is why we need a respec option. In the current game, if you screw up your build, well…have fun either building another (and losing yet another character slot to this new alt character) or just sticking with your gimped build.
Complete waste of Iso on 1 Star covers.
Yeah, its frustrating how bad the numbers are on even the promotional covers.
At this point i have gotten enough 1* covers to max them all several times over.
Maybe a second of certain covers you find useful. It does cost a lot of iso to max one 1 star covers, but they could come in handy in tournaments for when you run out of health packs and are waiting to get more.
