So a common tactic is to split off 99% of your army to avoid range damage, as the attacker will be targeting the 1% original unit
Now this is bad on its own,
I ran into a player that can make my planes have "no target" so i cant even do any structure damage.
A fix for this would be that if a stack is split, the planes or arty target the bigger unit
anotherway around this is so that the bigger stack is the original unit, which makes sense on a realistic level also.
I really want a fix for this because its such an annoying hack,
I wait an entire hour to do some vital damage and in the last second "TARGETING: NOTHING" deals no damage, and flies home.
