Are the Water maps just not used at higher costs?

[DRCEQ]

The Military Port, Jungle, Port Base, and Mountain maps seem to be completely absent from the possible maps after the 350 cost mark, or at least very rarely.

My experience with the game's RNG means I'm almost always playing Impact Site, Colony Drop Area, Arctic Base, or City Ruins more often than anything else.

Is there some kind of algorithm that makes sure that certain maps are used more often? I almost never see anything else unless it's specifically that map type for the map cycle.

Certainly never seen Military Port at 700, and that would be fun.

Ive never seen any of those maps at any cost, it feels like they just arent in rotation

1. There are very few native high cost units with Underwater affinity, which makes them really sluggish to be used in water maps

2. Since many of high cost units got very large size and hitbox, there are some parts in a water map like Port Base where those units can't fit/getting stuck

During the initial release of the Military Port map, the devs literally shoved that map on each and every costs into the map rotation, including high costs ones.

But then the players were complaining hard about it, because it was really bad, due to the #1 reason that I mentioned previously, which makes everyone using transformable units that can fly to do flybys or dogfight, instead of fighting underwater, so the devs decided to just remove the maps that focused on water battles from the rotation for high cost rooms.

All of these could change in the future, because the devs just released a custom part that gives Underwater affinity to the unit via special missions that lasted for 2 weeks, which solved some of the problems, so who knows?
