I used to be a WoW fanatic even back before the first expansion. It was grueling in some ways until you discovered some of the shortcuts, easier ways, and ultimately found a good guild. You had to actually pay attention to learn...and typically were rewarded with a good experience if you have a group reasonably adept at the same.
Then all the easy-way-out things came along. Forget tricky shortcuts or easier ways to level or learning the pattern of mining nodes to run...now you could just throw gold at most of the problems and grind the others. I stuck around for 2 expansions if memory serves, left, came back a while, left again, came back to play a few hours killing time and realized it just wasn't fun anymore. Everything had to be equal like between squabbling children. Seemed like they painted an I-WIN button over the grind button.
Buy hey...keep paying! Buy this, buy that...etc. No thanks. Somewhere along the way I shrugged off the MMO world and found better games to play in RL (and no, not sports). I'll stick to hard but short-lived games games like the old 8-bit days (or kill some time with candy crush) and call it a day if I get bored.
