Went into a few different quests to test the new changes to epics on hard/elite.
Few things I've noticed so far:
Mobs hit for alot more (lowest I saw was 120 highest 169)
Mobs still have deathward even below 50% (sorry no instakilling allowed )
Mobs hp are complete **** (I can kite thru one blade barrier hitting for 550 a tick and kill them all)
More to come when I come across it.
