One dungeon per patch!?

[Shurrikhan]

What kind of accounting is that?

Diadem is being revised, WT is still here as far as I know (haven't done it in a long time), and Aquapolis has its counterparts in the latter expansions.

As previously accounted...

Gains: Counterparts of Expeditionary Missions, counterparts of randomized side-content, and the only unique thing SB brought -- ultimates.
Costs: Only the dungeon per dungeon-granting patch.

Really? Wouldn't it be more likely that only the unique portion was bought solely with the time saved from including a dungeon fewer?

A mere single dungeon per patch did not afford us nearly all of our side-content, as the original accounting suggested.
