Instead of cutting Ultimate from 5.5 why not cut bozja?

YoshiP said a while back that things are built way in advanced. They thought it was a good idea to prioritize a 48 man that's locked behind casual content over ultimate content which people have been waiting over 2 years for.

As I mentioned on the previous page, these aren't likely two competing assets.
Development of the new Ultimate most likely impacted progress on the upcoming stat squish far more than Delubrum Reginae. In fact I wouldn't be surprised in the slightest if entirely different people worked on the fights.
Ultimate's don't really require much in the way of new graphical assets, it's more of a balancing project.

Also the last Ultimate came in patch 5.11, not 2 years ago, barely over 1 year.
