What i would like to see, is a test server for Strategus Castle and Town maps.
This could also be used to test strategies.
Only those would be in rotation.
Every map would be online for 30m-1h,
in that time people could build catapults and shoot the crap out of them.
Try different other siege stuff and see what would work and what not.
In the end everyone who sees there are no walls you can just walk through or, invisible walls or other issues, can then vote if that map is buggy or not, like the voting for map rotation on the offical server.
When map is fixed it would be taken out of rotation till everything is at least once fixed. Then the process starts newly, to find more issues.
As there are also issues with other maps, it is imaginable that all strategus maps could be treated this way, but i would set the priority onto Castles & Towns.
If all maps would be fine, then a voting could be allowed, so factions, can go onto that server and test a strategy before the actual battle would take place. There are already some servers set up for this purpose, but smaller factions clans without the manpower and know how often don't even know about that.
