You kinda need the 3rd leader skill for the hard badge not to take ages, even though I don't like using it. And an upgrade to distribute the damage over the whole squad would be nice, to prevent a leader KO. Lastly, the 'team up with 15 ... challenges' seem bugged, because I teamed up with way more units than the game actually counts. :( However, I have this urge to keep playing this game...
The squad start in this game is just one big miss; it makes the game lagg and even freeze at times and it makes some 'running challenges' harder than they should be.
