I am following up on the concept Liquid Maximum had on his stream about releasing a single-boss raid mid-patch.
His idea was: a single boss, released on the tournament realm only, at the same time for EU and US on a Friday. Difficulty similar to Mythic Tinral. No dungeon journal. No testing. Let all guilds who sign up kill the boss. Stream it on Twitch, etc.
I really like the idea, especially the “no dungeon journal” aspect and the simultaneous release. Watching the best guilds to figure out the mechanics would be huge.
At the same time, his idea was to not release it on live servers. This is something I personally don’t like. I don’t see why, if this single-boss raid is released to bridge the time at the end of the last season this tier, the competition should not be on live servers and be accessible to all players.
By this time, everyone has more or less the same gear progression, and if the release does not come with an item level jump, but instead the loot of the boss is maybe just a sick transmog or mount and a title, then no splits, etc., are required as well.
Also, pushing the boss to the servers with a reset, and then opening the raid at the same time for EU and US would not be such a big issue, I guess. You could lock it behind a quest that only becomes accessible at a certain time.
