if you let your cap get spawnkilled, its your own fault. just give up that cap and attack from another front. you insisting on pushing out from an area they have secured is just stupid. instead of spawning from that cap, spawn somewhere else and attack from behind. if you insist that the enemy isn't capturing the objective, you have time to sneak up and kill him, especially if hes focused on aiming at the teleport.
take time and think instead of rushing to the "forums" for backup lol. "i'm gonna go tell the forums!!!" what the hell is this place gonna do? just report things to me on RTB (which you didn't do).
