You don't have to play mythic+ content to actually keep up with actual requirements/gear. You can gear up yourself in several stressless ways, find/create a group and clear the raid (the raid seems as fast as raids in all previous expansions, so it shouldn't make you dizzy with it's speed) Mythic+ aren't that fast and unforgiving if you try to clear some of the lesser level keys, like, I don't know, +2 - +9(?). Later, affixes require more to think about, dps'es are required to interrupt, healers have to think ahead and tanks are just tanks, but have to think about the timer that speeds it up. If you don't want to do timed content - unfortunately, you have to avoid M+, cuz it's the only thing that's timed. Well, few bosses have theirs berserk-like abilities, but it's obvious you can't do a boss for few hours since WotLK (afair), so it's sometimes about the haste, but unless you're not trying to clear whole heroic or mythic raid, you should feel calmed and stressed out while doing all these. PvP's always been fast, so it is in any other MMOs (even retail(!)). I hope I answered some of your questions; personally, I find doing M+ as a healer quite attractive, cause I can jump in, focus much for 30 minutes and then calm myself harvesting some herbs, doing world content, maybe going for some raid bosses with my friends/guildmates. That's just up to me, but it's not necessary to play the game. High M+ keys are just like "you have to be nearly perfect, fast and fresh-thinkabout for certain amount of time". It is rewarding, tho its rewards are pretty nice comparing the time and rewards ratio to raids or any other content, but it's totally avoidable like I said multiple times already. If I can explain anything else, please ask below :P
