What's especially funny...or infuriating, depending on which side you're on...is when one team gets a load screen and the other doesn't.
The other night my buddy and I were launching an attack on seven blues from a tower. They just randomly stopped. I didn't really realize the keep had flipped...at first you think maybe they don't see you're hitting them, then your hits don't register combat text so you think the game is glitching or you're crashing. In the fifteen seconds where we were trying to figure out what the heck was going on, I think they were loading screen. Then, BAM, they're back, they all take like eight hits each and all fall down dead. I'm sure they were PISSED.
I'm not sure what the answer to that is. On the one hand, I wouldn't go out of my way to take advantage of the system like that and those are cheap kills. On the other, it's hard to tell when that's happening, and they get to respawn at the keep with no permanent damage, so it's not the end of the world.
