Now, I don't do a lot of 10 man raiding - I've stayed 25 pretty much since I switched guilds back in Cataclysm - but I know from experience how it feels to have that stress on your guild, and I find the idea that Mythic raiding will be out of the reach of some players not because of their skill, but because of the numbers game a little sad. To hear players that have been doing heroic content for two or three expansions now say "I guess we're done with that kind of thing" seems a bit off to me. And it dovetails into another idea I have, namely this - not all fights work as a hard mode in the first place. Some fights feel epic and really different with the addition of new elements that we see in a harder mode (Firefighter from Ulduar comes to mind) but others just feel like the same fight with more damage and health - and those fights to my mind don't need to exist.
This has me wondering - do we need Mythic raiding at all? Going into Warlords of Draenor, we're looking at LFR, Normal, Heroic and Mythic raiding. Four raid sizes, each aimed at different kinds of raiders. Yet all four of them present the same basic content, simply scaled differently - the same boss fights, just on a different scale of difficulty and (in the case of Mythic) presumably some different mechanics. What we're seeing right now in Siege of Orgrimmar is that for some players, this is contributing to burnout - saying 'hey, go do heroic if you're bored' doesn't help when heroic is the exact same content, just harder. Do we need more of this?
