First of all I have no issue with f2p players. Some will be good, some will be bad. Same as new people who pay for the game. Or do you think nobody has bough a copy in the past few years since the release and only players with years of experience exist? I've bought the game nearly a year ago and have since only played for around 20 hours. I just didn't feel like playing it then. Now I'm among the first players on every map I play and routinely own players with years of experience.
Second, I'm not sure how good and reliable the system is and if it can keep out only f2p player, or if it will screw with other people. How about people with premium accounts that upgraded by buying from the steam store? Any purchase, no matter how small, automatically upgrades them.
Lastly, what about a year from now? Is there still going to be this f2p bigotry bullshit? Considering that after a week of play I'm always in the top half of players (so therefore better than most players) is the noob argument even valid?
Skill levels always vary, and the general distribution of good, average and weak players will be fairly even. That being said, I find this mod very stupid and helping to perpetuate a very stupid issue.
