So I quit shortly after MoP release and every once and awhile I hop on MMO just to see what's up in WoW and all I can say is I can't believe the amount of changes that are constantly being made to game/class mechanics. It's truly mind boggling and if I actually wanted to play again I feel I'd have to spend an entire expansion just catching up on the class changes alone.
It would be like if god came down here and was like, "Ok kinetic energy is no longer 1/2mv^2 ... were finding that those who are faster than others have an unintended advantage so were changing it to like ... 2/3mv*2. Have fun! Oh shit changing that formula fucked with a whole lot of other things that we should have realized were connected but didn't. And those who spent all their playtime getting faster now just had the rug pulled from under them... And so on and on it seems to go.
Just saying it's pretty peaceful and hilarious now that I'm no longer affected by it lol. Every month or so when I hop on I'm like WHAT!? they changed it back?! They made it more/less!?! lol
Have fun in your "World of Laws of Nature are constantly changing WarCraft."
