I recently stopped playing because of the extreme irritation of the 2nd LFR wing. Even though the proper tactics were being constantly "raid warning shouted", people still didn't listen. This was especially obvious on the General Nazgrim fight.
It got to the point where I started being genuinely angry. I didn't like how that made me feel so I got away from the game as quickly as possible. I've known from before with ToT that things always suck in LFR for the beginning period, but at the time that fact did not register. I just felt so angry at the incompetence of LFR; it is ever-present regardless, but that day was especially rage-inducing.
I didn't know what else to do but leave. Now I'm hesitant to even play again, knowing that LFR-incompetence, as well as the gear-treadmill thing, will still be present if/when I returned. Just wondering if it is worth returning to play WoW, or if I should not come back at all.
On a small note, I am aware of addons that can turn off the chatbox entirely. I guess a good chunk of the rage-inducing factor does stem from that insufferable tool when in LFR.
