Agreed. This late in the xpac, wiping because the tank doesn't know what to do is maybe the worst thing to happen to an already shitty LFR experience. Asking people, who might have been occasionally helpful, to explain stuff in LFR after they have been in countless wipes, in the preceding months, to shitty tanks, usually from Brazil, that cant speak English, is like asking a dog to do your homework for you.
But no, people would rather queue for the 2 most important jobs, and wipe because they dont know mechanics, or just suck at them, to save 10-15 minutes on the DPS queue time, because hey, fuck everyone else's time, right?
Edit: If anyone didnt know, you can queue for all raid LFRs at the same time, so you only have to wait for the first queue.
