Unless I'm missing something, this new dungeon really needs some improvements. It's a gauntlet of 8 trainers in a row without access to any healing beyond consumables, running around in the same monotone maze in order to reach the interesting thing: the boss.
It'd be okay if we only had to do it once, but you have to do this repeatedly in order to see all the dungeon bosses. Even that might merely be tedious, but I've done it two times now and gotten the same boss twice, so you can also get fucked by RNG. Really like the game but I ain't touching that dungeon anymore without some QoL.
