And as I pointed out earlier, that would be perfectly fine if there was a full set of possible gear available from the later bosses. The idea of "You need gear from the first 6 bosses and you'll replace that with gear from the next 6 bosses" is quite cool in theory, but in practice it doesn't work that way because there aren't two distinct sets of every item, one at low ilvl and one at the high ilvl, they've just got one set of HFC loot arbitrarily split between the bosses.
They could fix the problem by adding more items so there's a full tier's worth of loot in each bracket... but I don't see that happening because each boss would have a pretty giant loot table in that case.
"My loot is better than the loot from last tier!"Even the crappy ilvl 720 gear that won't get used is still 20 ilvl's above Mythic BRF...
Great, but that's not a lot of compensation when your friend who happens to favour different stats gets loot 40 ilvls above Mythic BRF just because his item happens to drop from a later boss than yours.
