So as I've written, recently I've again tried to somehow force myself to transition to Beast Mastery, at least temporarily, in order to supposedly do the right thing for my new guild.
We did a Black Morass less than an hour ago though, where I was using the dreaded macro, and I found myself thinking afterwards; I might as well be botting. The playstyle with it is completely mechanical; I actually wondered why I needed to be at the keyboard.
It also therefore reminded me what I've felt before; if I have to use BM in order to raid, it's going to literally remove whatever motivation I have to play the game at all. So I respecced back.
I've seen a few people leave WoW, recently. Rilgon because he couldn't be Marks any more, at least partially. Efri because his account was hacked and I think that removed a lot of his motivation, in conjunction with other things.
If I look at it, Survival is actually what keeps me playing this game. The promise of new gear doesn't; gear is only a means to an end, not an end in itself. The promise of new content does to a vague degree, but not enough to keep me playing by itself.
Survival is what holds me here. If Blizz break the tree, then I'll leave too; but as long as it's intact, probably nothing else will cause me to leave.
