We don't (at least not ones I know of) choose based off assets. There are so many factors that go into setting a map - Player count, player skill, new players, old players, frustrating maps that will make new players leave and way more. We don't enjoy doing easy walk in the park maps either, it's boring. For example, we tried to play Charlies Point the other day with only 20 players, because we wanted a challenge, yet we had to run next because the rest of the team was fairly new and we were being slaughtered and ended up with about 10 players left.
It just so happens that the maps that are much easier are asset heavy, unless it's an Inf layer where it generally feels very even.
TLDR; We don't pick maps because of assets, there are way more factors than that. A lot of new players leave harder maps and kills the server.
