They’ve already pruned down the gear it’s going to give to the point where your average raid clear per week will very likely result in more gear coming your way.
Then again, if you’re not amenable to temporary gear capping so as to not reduce incentive to gear in raids, what exactly would be amenable to you? You’re not proposing solutions, you’re simply playing the role of a “no-man”. M+ truly does have difficulties that are roughly on par with Mythic raiding. Are you trying to tell me that people clearing the first 4-5 bosses of Ny’alotha deserve loot more than people doing +20s? Particularly after the raid gets nerfed down?
They’re talking about the weekly chest for that. So you’re telling me someone who’s getting 10 chances [in Nathria] at gear from running, plus one guaranteed piece at the end of the week, is better off than someone whom [according to datamined information] will only be getting that Heroic-equivalent piece once a week, or will be forced into farming +15s for below-par gear and relying on the weekly chest for gearing?
