Seems like their are some items here already, but it looks like it gives credit to the first player to drop the totem to give the corpse the buff first on the treants, rather than allowing all taggers to get credit for the buff, so makes it a bit contentionous especially with so few spawns, so please fix this! 
This quests if bugged needs to be fixed or removed until it does get fixed because this is garbage the way it is and looking at wowhead has been a problem until at least 20 December and no way it hasn’t been reported in all that time.
Two days dropping by to get the occasional lucky credit because some Johnny Awesome wannabe will drop right on top of your fight, plop down a totem and yay they win. Also try using the totem during the fight it’s interrupted, but Johnny Awesome still gets credit so at least someone got something out of it.
