I fully agree. Unfortunately it was already stated in announcement post that Omen Windows are going to be bloating the maps even more:
Omen Windows appear as a new type of random encounter throughout both the campaign and the endgame.
Also why in the campaign? Nemesis, Rift Beasts, Loot Lizards and the like completely disturb and derange the character progression even more than it already is. If campaign is reported as boring, fix the campaign and the dungeon skip system. (Champions I find interesting though because they are “unavoidable” and a danger early on. They don’t feel “bolted on”. Exiled Mages are redundant anyway for the most part. Should be reworked too. So much work huh).
It’s also funny that you can select Weaver Tree nodes or run certain echoes to have Tombs, Nemesis, Rifts appear even more. They appear already on every second map regardless!!
