I had pug and down from pre-50 contects to T7 also all the em primals besides shiva, Maybe i was lucky, but nerf T5 more is not going to solve the problem, people just need to work on and understand the mechanics. With echo, ilvl 90 group should have no problem to clear it.

I do understand T5 is like a huge road block for a lot of players, but that is also a skills check point for future contents, SE made it hard for a reason.
