Rant: Really sad that CoH2 automatch pool since 2016 or so followed this trend of just looking at map pickrates/vetorates and add or delete maps based off of that.
There are a few different things that pushed maps towards the laney stuff.
1) Players need to blame something for their loss. Weird map? Blame it. Some trickier to play maps were made and they were universally hated. People were even told "Make an open field map. We are not looking at anything else."
2) Players only have three load outs. They want three useful commanders. If the map is too weird, it requires a certain commander to be viable. Which takes away from your other commanders. The game should have been designed better. If your infantry could be focused short/long by upgrades would help a lot. This is partially Relics fault by design.
3) Many players want to use a variety of weapons. If the map is too much of a maze you cant use team weapons at all. AT guns, for example, become useless. Now you have balance issues for team weapon focused factions.
4) Mappers only get one shot at making a map (unless you are WhiteFlash). You have to make the map as safe as possible. You cant risk people hating a section that is weird to play cause your map will get removed rather then reworked. This is Relics fault. Their apathy towards their own game.
5) Some players just like to play a certain style (A-move???). They will veto certain maps.
ANSWER
Relic needs to be much more active with the mapping community. They need to add maps more frequently and let mappers update them. Instead Relic is saying "We cant add maps cause we have small pee pees". As usual, doing the complete opposite of what they should be doing. I dont know how they stay in business. What other type of business can you be completely incompetent and stay open?
