Heroic fishes!

Zakuun was another boss where we barely bothered with the proper tactics when we came to do it on normal mode - On heroic mode trying the same way ("stand anywhere you like, sort of spread out, and just nuke") results in a very dead raid in very quick time. We started again by learning the proper tactics for each ability one at a time - apparently I confused many when they thought I was asking them to stand in "fishes" (and not fissures as it says in the dungeon journal!) - Anyway eventually we solved the riddles with fishes, fissures, and the debuffs you gain from them! Thankfully it didn't take us too long to re-learn the proper way of doing this one otherwise this might have read like something from Dr Seuss!
