Yorcia was cool as a concept, at least in theory. The problem there imho wasn't just the event itself but the fact it didn't "scale" with the quality of your group.
Which is what happened in Cirdas and Rala. Bad groups struggled with making it in time (on high levels) and good groups ended a run in 20 mins.
In Yorcia you had fixed waits no matter how good you performed, and that made the event pretty frustrating and boring.
They added an option to cut times but it came too late and didn't completely solve the issue anyway...
Regardless, looking forward for this

Did you notice if maps are generated "randomly" for the same body tier (like Alluvion Cirdas/Rala) or if there's a fixed map dependant on body tier like old Skirmishes?
