I don’t think the problem with a map pool is having too many “non-standard” maps.
I would say that the problem is specific maps themselves, not matter if they are standard.
For teamgame mappool:
Hill Fort, WolfHill are non standard and 1 strategy on a competitive level.
Black Forest, Scandinavia, Hill Fort, Lombardia are standard and 1 strategy on a competitive level.
You see the same civs on these maps.
A non-standard map that would not fit your way of defining a boring, one trick map would be the Golden Swamp.
- I would say a countable way to judge how bad the map is would be to measure how much elo you gain on average (how much higher rated are the players you beat) when you select one of the top civs (or literally the top civ) and your enemy goes random civ (again - on average).
Right now team mappool is in my opinion the worst one yet:
2 open maps (Arabia, Wolf Hill)
5 closed maps (BF, Arena Nomad, Scandinavia, Hill Fort, Lombardia
2 joke maps - not competitive (Nomad - too much random factor, MegaRandom - maps divided by thin layers of water or forests or both / too many herdable or huntable animals, random buildings and so on).
From which the worst one (from this way of measuring -> 1.) are Black Forest, Scandinavia, Hill Fort, Lombardia) based on mine and my teammates’ experience.
