It has been raised that maybe mace is just a bit too good against light vehicles.
This might or might not be a metagame thing, so how about a little contest for finding a valid counter?
The rules are simple. There are two disciplines in which you can participate:
1) Defeating a single, well-microed Mace with a group of combat Light Vehicles costing at most 400 metal.
2) Defeating a well-microed group of 5 maces with a group of combat Light Vehicles costing at most 2000 metal.
If it is not possible to win the contest under those conditions, just submit your attempts and we'll see who scores cheapest.
Validation of submissions will be done in glorious honorable 1v1. I'm willing to bank any amount of elo by playing the maces.
