It's pretty funny how it's the same people defending this outright unblizzlike behavior. People with profile pictures of warlocks and warriors. Yeah, totally unbiased opinions here.
Do you people know that you can bug this feature by hiding INSIDE world objects, becoming effectively immune to damage? Like the catapult on WSG. You can hide inside it and nobody will be able to hit you. You can just stand there and wait for your team with the flag. Blizzard made it this way to avoid exactly this kind of stuff.
"But kronos is fixing awful things about vanilla that everybody hated"
Yeah, no. I like that feature. Because it makes pvp less drawn out. It's not about "skill". It's about being annoying and ending the fight at an arbitrary point, while your enemy can't do anything about it. On battlegrounds, where timing is crucial, this can be game breaking.
Besides, why the double standards? Maybe kronos should make Ragnaros not fire immune, so fire mages and conflag warlocks can raid without respeccing. I mean, everybody hated school immunities, right? Or any other issue that "everybody" supposedly hated, when in fact it's just a vocal minority trying to push the developers into altering the game to favor their class.
