Where exactly do you see that ? Normal quests only go up to 800 and mythics are 840+ and heroics are 825+. Looks still at least decent in line with quests capping out in wod at closely around 600 and heroics offering 630. Mop had 463 in heroics and and about 437 from quests. Don't see much of a change there given you are unlikely to end up with "just" 825 running legion heroics.
