Trying the current day's set of missions, and I'm just getting my butt kicked. I was definitely wrong about what drives difficulty, because I'm running into easy missions that are against guys at level 117. I guess that'd be fine if the heroes I have that are boosted were similarly high level, but the ones I have that are boosted that high have no useful powers (Ant-Man and Scarlet Witch. Both can be very powerful, but I have a total of three covers between them, and it isn't nearly enough. If my Scarlet Witch one were purple, that'd help a lot. As it is, she's basically cannon fodder).
It doesn't help that this event has most characters locked. Nor does it help that I jettisoned my two-star human torch the other day (I have the three-star with a number of covers, so I couldn't think of a reason to keep the two-star as well (they have identical powers)); that was definitely a mistake.
Meanwhile (and this is what makes it really stand out), my second game just tore through all of the missions without trouble.
I wonder... yesterday's missions went similarly at the end. That is, I was able to win the third-to-last one a couple times with my secondary game, but got my butt handed to me twice when I tried it with my main game. The levels faced were certainly different, which helped, but I mostly attributed it to a much stronger Ms Marvel (5 red covers vs three) who could dish out serious pain very quickly. Now, however, I'm wondering.
Today's, though, I was seeing differences of 10-30 levels in the opposition (the 30s, not surprisingly, were the ones I noticed first). Anyway, I'm not sure what to make of it, but it's interesting.
