But he himself has to bring 1000s of player into the upper echelons of raiding. He is the savior of WoW raiding!lol. Preach is probably one of my least favorite YouTubers to listen to.
They're not going to remove Titanforging/Warforging. It's insanely popular with the casuals and the only legitimate complaint that us Mythic raiders had was addressed already. People don't seem to understand just how rare and not worth fishing for a TF proc is.
Preach is an odd one because he doesn't understand that there is nothing that Blizzard can do that's going to make Mythic raiding more appealing. The high end of raiding was stagnant long before they even added Mythic difficulty and that's not going to change. They could remove all other forms of raiding from the game completely and it wouldn't inspire anyone to step into Mythic. We're such a small percentage of the game's population that catering to us would be an absolutely idiotic decision. The casuals prefer the game the way it is now, and they're what keeps this game afloat. Not us. We're here because this game has the best PvE hands down, we're not going anywhere. They can afford to tax us a little. They can't afford to piss off the casuals though.
The previous tier has been obsolete at the start of the next tier for a long time now, that's not going to change either.
If he wants to go back to the old way of doing things that the entire industry has moved away from, he's more than welcome to wait for Classic and see how that works out for him.
