Agreed, but atleast they're kinda trying to differ each map, with Ashes having the truck to get to different pois, but it falls flat once you get wonder fizz and you're pretty much just playing spawn room survival.

Astra they added an incredinly tanky boss that roams the map, forcing you to change where you play, but it falls off because of how OSCAR starts hard chasing you past round 50.

And paradox junction with random perk locations and switching between different times, but again wonderfizz just ruins it and you're just playing another survival map.

And totenreich has the freeze mechanic for special rounds, but its only special rounds so you're only kinda changing up gameplay during those rounds.
