[Ave]

rather make some alliance units that each alliance can build from the taxes.

they can be fast (used as last option), but not too efective (u can't win rounds just by colecting taxes...) there could be limits in this fleet(s) size. Make it max 3 alliance fleets. Weather you use them for def or att (fleet catches), I dont mind. and give access to this fleet for set bc/dc (which you cant change without time limit.)
