except the way i see it is that people will see that a mythic + system is there and they'll step into it when they're clearly not supposed to be there (just like every ex/savage piece of content) and the wave of complaints will start to flood in. then since it's just dungeons people will demand that either it get nerfed or given special consideration, when the devs have clearly said they're more interested in creating new and different types of gameplay experiences rather than just retooling old things. I mean look at HoH. there's a reason we don't have yet another iteration of this in 5.x (and we're not getting one either). it's because while it it was a slap of paint on the PotD system it got old real fast. putting their resources into Baldesion Arsenal was much better for Stormblood.

And then there's the problem of rewards for a mythic plus system. Every time this topic comes up i never see a compelling reason to do so other than just "the challenge of it". every suggestion i've seen from people for a reward for doing mythic+ hasn't ever been something that would make me say, "hmm I would like something like that to be a reward".
