Agreed, the zone system is annoying.
But switching sides to take zones back or to acquire other teams zones is wrong? Maybe it's good for the game, maybe it's their way of playing, maybe they are tired of Knights getting horded by real estate moguls, tired of losing every 99/100 maps, tired of endlessly logging on to find there is no fight because the other sides have 30% of their bases, I wonder how many unearned perks are generated on the other sides, maybe they're tired of that, no? To each all the tools they are provided with. How is this any different than a guy who was just fighting next to me, then he shows up 5 mins later (with a recon advantage too) on the other side.?
It's actually rather funny what happened. It should happen more often. It did exactly what they intended it to do, you see that correct? Isn't it all about whizzin in your/their Wheaties?
