Team settings

make an option for players to have a list of team settings where you can have set amount of troops for different reasons. I guess make it similar to the way haypi adventures did it. Might save some time from adjusting troops for defense and offensive strategies

Yes, a favorite attack list would be nice.
Example
Fav 1
Pikemen
Hop
Arch
Arch
Arch

Fav 2
Hop
Knights
Arch
Sorc
Cats

And so on. Different cities/oasis call for different sets of troops so this would be helpful.

I would also like to add that have settings like aggressive, defensive, balanced and custom. For example

aggressive: make all troops move forward

Defensive: stay back and wait

Balance: move 1 forward/wait or wait/move forward

Custom: your own choice of presets
