With t17 race closing down with several guilds managing to kill Mythic Blackhand, I really begin to wonder if this race is just simply too fast? I remember back in the old days of Vanilla and TBC, A single boss took weeks to kill. Yes, I know that these bosses were ridiculously over-tuned, and extremely few guilds managed to see the full content prior to a nerf. Blizzard has shifted its stance towards allowing more people to see the content and allowing more and more people to experience the things they make. However, that is the reason LFR, Normal, and Heroic exist.
Wouldn't it possibly better to have the mythic content also be ridiculously over-tuned at the initial release stages? Like having the bosses require an insane amount of buffs/skills/time/luck to kill, or having them be limited number of pulls (Ra-den, Algalon, ICC end bosses) Imagine how intense the race could be? The race for world 1st is something that I do not see ever going away from this game, so why not make things interesting. As by current standards of 5 guilds kills before video releases, we can use that as a standard for when the bosses get a nerf or adjustment. Or simply use time as a factor, every week or two the bosses get easier to handle.
In this manner, it extends the longevity of the current top tier content even further as the day 1 entry would be insanely difficult, but as the content gets closer to the next tier the difficulty progressively gets easier (to a limit) and more people gets to see it as the difficulty becomes normalized. Meanwhile, the race for world 1st becomes an intense, crazy, unpredictable journey.
