For me the issue is, that in attempts to modernize the WoW, they alienated the game for me, as I no longer feel welcome in the game. The kinds of game interactions I used to have are gone. Game wants to put me into some bounds that make me feel uneasy. It tries to force me into a playstyle I don't like. And, worse of all, they periodically are trying to remind that they did not forget about players like me, so my hope is not gone but they constantly fail to deliver those promises, disappointing me again and again. I'm in a kind of weird love-hate relationship with WoW.
