I missed this large outcry of binding being hard and I've read pretty much every post in the discussion thread, so not sure where you're getting that. I remember typing the kill post to our first cadeus kill when we were doing it in ak green gear. I had to double back and nerf my own post to say how easy it would be with any amount of gear upgrades. That has been proven with people clearing 1-4 in thirty minutes. In WoW even when things were on farm you at least had to pay half attention to the fight. You don't for any of the mechanics in binding outside turn 5 and those only require only a little thought.

As for divebombs and twister being bugged, to qoute myself "The only two hindrences were divebomb which is still bugged, I dont believe making twintania fly off the stage is how they intended the fight, and twister which is still bugged, you live even if you're not doing it "correctly"." They're beatable, but still bugged in implementation.
