So did Koralon last night on 25man, on shot, easy mode. Boss is down, and we move to Emalon. One dumb warlock facepulls the Emalon trash while were doing loot. He leaves the raid, followed by 2 other DPS. Our DPS was high enough so we head to Emalon down 3. We get to the 3rd overcharge and the DPS fail horribly, several dead from chain lightning and one moron warrior from nova. Run back in and over the course of the loading screen we lose 4 more dps. At this point we are in shock that so many people just ditched. And of course no one is going to join a group with the new boss down so we have to abandon Emalon, which still had upgrades for several members and most of us could use offset/PvP gear. I port back to Dalaran and see several more complaints about this in trade chat.
Anyone else experiencing this? My solution is two-fold. Due to the new loot trade feature, I am not giving out loot until the very end, also will NEVER do Koralon first again.
