I kind of agree - You might not be ready for T6 if you can't handle T5, with or without the echo buff. T6 is a rather intense fight, requiring good coordination of a party to be able to clear. T7, I haven't cleared yet but we've gotten to 50% - it feels like it's getting more and more intense with the coordination and timing (DPS checks everywhere!)

And honestly, people have way more advantages over those of us who cleared T5 pre-nerfs. Just like we had advantages over those who cleared it before 2.1 and before still those who beat it before Square Enix 'changed' Twister mechanics.

They'll keep making the fight easier and easier until people can clear it. But right now, it's fine the way it is - They're gating it, but they've made it rediculously easy to pass once you know what you're doing.
