We were doing heroic last night with 29, and only getting 2 sometimes 3 tier pieces. Is this common for anyone else? Has it always been this low? I would have figured it would have been closer to a lot of 4, some 3 instead D:
As far as I was aware it was 10% chance per person for tier. 10 people get 1, 20 people get 2, 30 people get 3, 25 people get 2 with a 50% chance at a third, etc. I could be wrong but its always been a little on the lower side since tier is a guaranteed drop, so you'll flush them out at some point.
