I would prefer if it wasnt actually a hill but maybe a small fort in the centre of a map or just plateu in the centre of a map.
Anyway flags spawn at the start of the round. Whover either survives or raises their flag wins. It doesnt require new maps allows open maps to be used without cav or ranged victims crying and keeps each round short and sweet.
You will not win without a balanced team and team work. It also doesnt require any special points system or respawning.
Just two ways to win a battle.
