Ah yes, the calcium boys definitely were a bit on the slow side. And I aggree the 4v1 fight is a little tough on marsha, depending on what augments you got. (It's much easier with Therese, since she can block Lunesis and Moogs, Marsha is hard mode after all.)
It was a little tough balancing the game around 3 different playstyles at the same time, so I'm not really disagreeing with your asessment and the real game is probably gonna do a better job on the balancing part. Cheers my dude :D
