1 death is better than entire group wipe or messed up cooldowns in future pulls or a boss.

Only 1 death? Oh man, I'd love if the YPYTs I've seen only resulted in 1 death. The way things usually go down, I'd almost think they're just wiping the entire group out of spite. No way, right?
Also what's with the assumption that the "offending" party is always a DPS? What's the logic behind "sacrificing" a healer?
