Please consider slowing, count per and/or HP of adds on 4th name (Pri'ki'ori'ki - calls 4 at a time) in this zone.
Actually, this is a bug. The first pair of adds should stop spawning after Wa'la'kra'na is killed, but I had it checking for Pri'ki'ori'ki's death instead. Whoever named these fish heads should be demoted! This is fixed now, but will require a new zone.
