My suggestion for torghast means it is entirely optional so it would be as good as removed if you never wanted to play it. If you look at my suggestion on my other post i think you might enjoy it, and even if you didn’t. you’d never have to do it.
Regarding LFR, i see LFR similar to that of Honor Gear where it is simply entrance level content. I wouldn’t put the tier set in the LFR however I would suggest the removal of Tyrannical and having Tier Tokens (up to Heroic Level depending on the M+) to be rarely dropped inside Mythic Plus chest, which could offer a slightly alternate way of getting the tier Set without having to spend time raiding. Would you be happy with this?
