There are three problems for me associated with this update.
First, it divides five gametypes right down the middle by limiting standard players from half of the maps. Anyone in any of the standard five gametypes essentially has to have premium in order to be competitive. It's absolutely idiotic that half of the game's content be limited to those who pay for them.
Second, the interruption advertisements for standard players. There's a big difference between giving great content to subscribers and UNNECESSARILY HURTING PLAYERS' PLAY EXPERIENCE IN AN ATTEMPT TO FORCE THEM TO PAY. Yes, that's yelling, because I am that infuriated at how id uses such a roguish, low-blow business tactic. No money of mine will enter id's hands for Quake Live until that abominable practice is ended.
Third, and finally, there's the issue of payment plans. I'll buy a card at a gas stop for even a year's subscription. I will not use credit cards, debit cards, paypal, etc, under most circumstances, and I'll never "subscribe" to a game; I might buy a month of pro/premium, but I will NEVER subscribe to ANY game.
Changing it to a quarterly/monthly charge doesn't fix any of those problems.
