Bosses have about 200% more HP than they should. LFR raid does NOT offer the level of rewards commensurate to the bullet-sponge nature of the bosses and the absolute brick-brained stupidity level of the average LFR DPS.
If this was giving 606+ gear, ok, but it’s not. You need to kill EVERY single miniboss from EVERY wing just to get enough currency to buy ONE crappy ilevel item.
Simply not worth the hassle. I just ate a dungeon deserter debuff rather than sit there and continue to heal terribad DPS who can’t follow basic mechanics or, you know, read.
