It’s all about experience and how much you like playing the damn game tbh. While I do premades with some friends, yes we use mics, but that’s not the reason we win. Mics we use just to chat and make fun of things etc 80% of the time, we win because each knows his role we focus on fulfilling it. I can play with pubs this way just as well, problem is most pubs just don’t have enough experience/willingness to learn/improve. Most still don’t know how to manage jetpack fuel, dodge abilities, swap cloaks, not push alone, SPREAD, etc. Most pubs suck just because they’re not as experienced as players that make the effort to organize.
Edit: Your question is made better maybe if you ask “Is evolve fun for casuals?” Well with the new matchmaking system, maybe it will be. With the old one, not really. Now at least if you are bronze, you should fight bronze monsters. Casual monsters.
Edit 2: It is also hard for pubs to improve because there is no real drive to do so. It doesn’t matter if you dodge like a boss most of the times, if your team just dies while holding eachother’s hands from 1 vortex + 1 aftershock in 3 and a half seconds. So you are not motivated to actually play well. After a while of game after game like that, you just give up and get the opinion “monster op”. People in a group tend to compete with eachother, nobody wants to be the weakest link in a group of people that know one another. So they improve and improve and improve.
