I don't think it should be required of me to stick to level 1 just because you're not fond of people who aren't that skilled at the game. Fortunately for me and others like me, VMK doesn't feel that should be required either.
You think some of us are overanalyzing, and some may feel you're overreacting. All in all, it's just a game. The credits aren't real. The items you buy with the credits aren't real. It's not like the game somehow requires so much more strategy the higher the level, you just better prizes in level 3 if you're lucky enough to get a chest that actually has something in it. There are good and bad players at every level. If this really does bother you, choose your team before you play. Otherwise, it's going to be a reality that if they've made it to level three, people have as much right to play that level as anyone else does.
