Every single time I tank the Klaxxi Paragons fight, I think to myself This is a really weird fight. Between it being a council fight with nine bosses (three active at a time) and with it completely negating AoE (every time one dies the other two that are up get healed and a third one drops in) plus the stacking buffs that make it a bad idea to leave any one of them up too long, and each one adding new mechanics that need to be dealt with, it's just a weird fight for me to wrap my head around. I can grasp some fights just fine - Spoils, Norushen for instance - that have strange mechanics. But while I can tank Paragons just fine, I don't pretend to grasp the fight as such. It's a weird fight, I don't really get it.
Any fights like that for you? Not just asking for SoO - did you find fighting Kologarn weird, back in Wrath? Was Cho'gall a mind-twister for you? What fights make you just throw up your hands and say 'whatever, let's get this over with' the way Paragons does me?
