Active good attackers might hate this idea.. But if we get it it makes it more easy to play the game for inexperianced players..

If you can make 1-5 pre selected fleets That would mean bankers can send more easy.. Each attacker knows how ennoying inactive bankers are.. Now it is more easy for them

For instance,

Fleet A: 3 sold, 1 trans

If you click on the planet than on attack there is a fleetA button

Pres it and instantly send

Benefits: bankers take planets quicker and more Often wich Gives attackers better moral. Also this would make the game easyer to play on smartphone and creates more overall active fams.
Retakes Will also be done with more ease
