do wonder how may of the players who complain about the +/-2 MM realised that they'd never be 2 tiers down, but never 2 up either.
I do, and to be as [edited]honest as possible it's totally worth it to lose the ability to stomp on people 2 tiers below me to not get it done to me on another day. I don't get off on being functionally immortal in a Scharnhorst against a New York or making a Bayrne worthless in an Amagi. It's a) not a good sign that the ability to exact the same unfair punishment on someone else is worthwhile in ruining other person's good time, and b) it's not worth it in the long run, which is what people need to think about, as it will kill player retention and make it harder for new players to start.
I can speak of my own experience in WoT to testify to this. I was a Warthunder guy, have nearly all tier 5's in all trees, but after playing WoWs I figured, hey, give WoT's a try. The T3 is brutal. Just, brutal. I think I've not been bottom tiered like once. And after about 2 dozen games playing that way, I gave up. It wasn't worth the effort. That's one less player retention in the long run. Now WoT's is starting from a MUCH bigger pool, but WoWs isn't, and we need to think like that, or boy will some people feel stupid having spent the money they have.
