It could be possible for a faction with few rooms but mostly legendary rooms to have a better upgrade chance than another faction with more rooms but mostly common.

But between Hall and Eye, I think you’re right. Here’s my attempt to calculate the chances:

> 
> If the All-Seeing Eye always has entry, boss, 1 legendary, 1 epic, 1 ultra rare, 2 rare, 1 common, then the same calculation finds a chest level of 2.65.

Do those numbers feel right? At quality 0 that would be 4.2 and 3.6 after defeating the boss, or 7.2 and 6.6 at quality 10.
