Hey all, I just downed Garrosh in LFR today (amazing cutscene btw), and I noticed that after we downed him, we got the Strike! Achievement Strike! - Achievement - World of Warcraft . As you can see, this achievement says only in flex, normal and heroic, so it is currently bugged and you can get it in LFR, which is one less achievement to worry about when trying to get the Galakras Mount!! Have fun.
