Like @Pr8Dator, I play ‘HonestMan’ - essentially IronMan with backup saves for when the game crashes. And I too have yet to encounter the swarms other people are encountering.
I’m starting to think that the dynamc balancing mechanic is doing things wrong - instead of spawning more Pandas vs players who are doing too well, it should be evolving smaller numbers of Pandas to deal with the Squaddies’ ‘broken’ abilities. I made some suggestions in my own feedback thread, so I won’t repeat them here.
Like the OP, I am really enjoying the game, but feel it still needs a ton of work. I get the feeling that they released it around a year early, either because they had contractual obligations to Epic or simply felt that they couldn’t afford to delay any longer.
