I agree on mythic plus. A good way to challenge yourself and get gear.
I blamed plus on the hurt raiding is curre tly in, but it is not just that. It was pointed out to me by our raid leader that tier sets as well.
This is why plus co existed with raiding so well in Legion. He then told me about a Pali doing plusses in Antorus set gear. No way the gear should be much better. 3k rating though.
