I like power suits to offer protection from chryssalids as well, so that there's still a choice in armor rather than one obvious best option for all cases.
In some other forums or threads some did complain about the flying suits giving that advantage over the chryssis:
Its always nice to have choices, maybe I myself would not mod the chryssis, no, but to have another creature to do a similar effect but be limited by armor could be nice to have.
In some ways it's like my experiment spawning civilians from dead civilians that automatically turned hostile, which is undesirable for what I had in mind. Maybe the civilian spawn as described is a bad idea, however, the effect to have an allied tank crew spawn from a blown up vehicle would be useful, that is if the game could spawn units that way that did not spawn hostile.
The demo that was released around the time the game came out, I must have played it about 18 times, could not beat it once, came close , but always a CHRYSSALID inconveniently appeared, zombified someone and the game went south from there.
