I don't even have 1 kill on LFR or anything. I think I went 7/7 heroic in highmaul and 1/10 in BRF heroic before I just quit from the shit.
Retired hardcore raider since realm firsts ulduar in 2009? Shieeeet the casual life offers room for so much more stuff to do! (proper meal timing, proper exercise, reading, chillin, watching twitch tv casually) .
Congrats tho man if you really love it then do it up. Me personally I would feel guilty for wasting so much time doing that one single activity so I'd dip out after probably 10 kills. If you still find satisfaction out of it and aren't doing it out of just boredom and habbit then props to you
