If you use the Salyin Battle Banner on Ji-Kun , the warscout will taunt the slime pools and move them towards him temporarily. This could be useful if you want to soak up multiple pools at once, or get people killed in lfr by surprising them. I suspect it works because the slimes might be "dummy" npcs, so perhaps this could work on other fights too.
