Wasn't sure where to put this; into the Suggestions forum it goes.
I did a Tier 3 terminal run about an hour ago - 4 depth levels, including a Treasure Vault level and an Aurora Isles Jelly Farm level, and I emerged at the terminal a shade over 2k crowns richer. After the Wolver Den level alone, the first of the four, I only gained around 200 crowns. I appear to earn more doing T2 terminal runs than T3; on average I earn about 4-5k crowns (all numbers based on solo runs).
Is this intended? Should we be earning less in T3 than T2 content?
Are you comparing similar levels? Like, I get more crowns on an L1 arena than an S4 deconstruction zone. (But deconstruction zones give an incredibly low number of crowns in my experience.) [Kudos for specifically checking odd strata only. Four random data points {as opposed to non-random jelly castle} I collected suggests that you get about twice as many crowns from the second stratum in a tier than the first, which would further skew data.]
As far as treasure vaults go, I consider those good if I get more than 500 crowns off of them. Those are mostly there for the chance of getting tokens or equipment, I'd say.
