Why are arena, black forest, and amazon tunnel ALL in the team map pool at once?

If we include hideout that's 4/9 closed maps. Of the remaining 5, one is a water map and 2 are the "wacky" maps (nomad and megarandom). That leaves only 2 standard maps.

I'm not saying every map needs to be arena. But there are plenty of normal or hybrid maps they could have included.

The one game I played on amazon tunnel lasted 2.5 hours and only ended when someone had to leave. This map is the only reason I hope they don't fix dodging. Who in their right mind thought "you know, black forest is just too open"?

I know arena and BF have their own drooling playerbases, so if they're in the pool I can accept it. But there's no need for 2 variants of each...
