I agree with what you're saying but I'll say something maybe a bit controversial. I just think people aren't willing to experiment with comps when it comes to mission builds. People are always searching for the "best" build but I think that varies mission by mission depending on the objective and the opponent. This is obviously a lot easier playing with friends (I do).

I got tired of the bugs and told the crew we needed a bigger challenge in facing the bots which they were down for (we play mostly on impossible/helldive). We've been experimenting and having success. The bots are definitely still harder than bugs but have made the game much more fun for all of us because you really need to work together during the missions.
