I dunno bout the matchmaking system somedays...
I joined a Clan Arena game the other day which was 3v3, and holy fuck 2 of the people on the other team were just nailing me constantly with rail guns from a good distance out.
I mean sure I could get into a groove every few rounds and run up 5 rail gun hits in a row, and got a "double kill" one game, but fuck they were just constantly outshooting me across the map, and if it ever got close with rockets I was never able to hold my own 1v1. It seems like a good amount of people "play down" in games, just so they get matched against people like me who don't know the maps for shit.
I have been accused of aimbotting more times that I can count with the railgun, and I'm still in tier 3. I think certain weapons just confuse people more than others and so someone being really good with a gun they aren't as good with makes it seem like that person is a lot better because they have no way to combat it, I dunno.
I mean, people play down on occasion, I know, but I am pretty sure you can't play down "too far" because I have heard some people say that they can't join games because they are too low.
I dunno, they'll probably revamp the ranking system several times in the course of the game's development, I'm not really worried about it and it doesn't happen all that often.
