So we will just assume no one quit and the playerbase is the exact same as it was during other periods in WoW's lifetime then this is absolutely abysmal and should be rebalanced and more likely rebranded to actually get folks to take that step into it unless you want the accountants to come for the cost analysis of a mode that is seeing the least retention rates. The numbers can be both ways and in a world that is largely cut-throat capitalistic guess which will be on the chopping block unless more people are nudged into it.
We have 377 guilds that have cleared Mythic Jailer as of July 2nd, it launched March 8th. Which is 116 days.
the 377 guild to clear Mythic Sylvanas was done on September 16th, which was 65 days. But to give you a better perspective the guild Rubicon on Barthilas Oceanic killed Mythic Sylvanas on October 6th which was 85 days but was kill number 598 but hey keep on slurping down the Kool-Aid that everyone loves raiding and that it will keep WoW afloat while we have evidence that less and less people are willing to put up with the bullshit that it demands for 2022.
The.Raid.Is.To.Damn.Hard with only using very little amounts of evidence but perhaps Sylvanas is to easy one would say we can go back to Castle Nathria to further prove a point to you if you would like unless EVERY ONE OF THOSE PLAYERS just got worse because we dont know if we have more or less players but we have to assume its even as thats all we have.
But for myself i just get KSM and fuck off until the next season as i cant be assed to spend more time then that on the game that does not respect my time. Another thing if they gut the Mythic Plus system to entice raiding more then i myself and a few of my mates would just not come back so its up to them to make me want to raid not pride or anything else. They have 17 years of experience with this so they had to know that the same thing happened when Cataclysm Dungeons got to be to hard that it would destroy their playerbase.
