Honestly, I'm not really all in for this echo buff business in coil BUT new turns are coming out. T5 is needed to unlock T6 and I would like to have more people being able to do T6 for when my static isn't raiding. I have a feeling my first few weeks of T6-9 pugs when my static isn't running is gonna be an elitist fare.

As long as T6-9 provides a challenge, the buff doesn't mean anything as you will only get outdated gear. Good thing is that, if you are trying to beat it first time buffless, you can cancel the buff out
