1. Make scouts detection range wide (try double 4000 vs 8000)
2. Tec Mine. Cost should be cheaper because they cant be used to as an offensive weapon unlike the other two races mine. Also mines should be allowed to exipre.
3. Advent mines: limited to how many mines are deployed base on how many slots a carrier selects to make mines
and or
if devs wants mines to be unlimited then do a time limit of long these mines can exist because they are free
4. Vas Mines: As with advent they are free so they should have a time limit like 5 mins.
