It seemed you suggested just that:
You're completely and utterly missing the point. I'll explain it once more and leave it at that: I enjoy (the challenge of) raiding but after I've cleared heroic once, I have absolutely no reason to do it again. Clearing mythic becomes equally boring after the third clear. I can't express it in numbers because that would require actual statistical research, but I know I'm not the only one that would rather skip raid days if it weren't for the carrot-on-a-stick.
So again, I'm not talking about "fun encounters" (you seriously thought flame of leviathan was fun?
), nor am I saying that raids in general aren't fun. What I'm saying it that repeating the same scripted content for months on end isn't. I consider Super Metroid the best game ever made, but I wouldn't complete it every damn week. Why? Because 'assembly line' activities are mind numbingly boring.
You think "
plenty of" people will still raid [mythic] after tiers sets disappear? First of all, what do you mean with "
plenty"? Do you mean "
a large amount"? because that would even be incorrect
right now. Or do you mean "
enough to justify development resources"? Because in that case I absolutely disagree. Mythic raid participation is already extremely low. High quality gear with exception of tier sets can be acquired through content with more variety, which requires less logistics and less time invested. Remove tiers from raids and I'm almost certain barely anyone will be instrinsically motivated to clear them more than a few times, if even.
Only time will tell what will actually happen.
I'm not sure you're correct with regards to pvp participation; I was under the impression that it's one of the most popular features of wow.
But indeed, it's what I said: wow heavily relies on the carrot-on-a-stick principle and I'm positive there are ways to shift priorities from gear to actually playing and having fun. Wow has done it a few times already: The tower bosses, the warlock green fire boss, soloing old content, class quests, etc. These are all forms of content that people do because they actually enjoy them and not for the rather insignificant, but fun rewards attached to them.
