So I bought premium last week only to discover there's nearly never tier 3 servers running and I get pwned in tier 4. I think this is a problem for many that would otherwise buy/keep premium that the skill level is generally much higher than in pubs.
It would be good to have 1 tier 3/2 premium server for CTF/CA/Ffa available to standards and then have premiums be able to go on a waiting list and have the standard players kicked from server when the next game starts. This way you can guarantee people that pay get some fair competition without giving F2p players the same advantages as premium players. This would motivate a lot of less-skilled players to keep paying because as it stands I'm not likely to keep paying for content that I can barely use due to lack of sameskill players.
