2700 is way to easy to get with the flaws in the rating system.
Love the concept of the game, and the no sound question in the beginning.
To get 2700p: dont die, get everything (Territory, upgrades, unique, and get fighting units to lvl 5), kill king. You should get more points for killing the king fast and not be be able to continue after killing the king to get everything and kill king again and get the extra points for your new stuff.
