Looks like Blizzard just rolled out some Hotfixes tonight. 12am EST.
- Currently it seems that they hotfixed all of the "quest" Paragon leveling. We tried on 2 different quests. Khasim Outpost and Adria's Hut (Explore the Cellar in A1). Seems after the 2nd time of doing the quest you are not rewarded the usual 11m exp on T6. You now receive only 3mil per completion. We experienced this mid-run.
