i like TD games alot so 5/5
but it would be great to add +1 ranged(magical) unit
for example mage - at a cost of 17 points with shorter range than archers and slow attack speed. With lightning attack - upgrades may be 5/10 cast speed, area bonus attack for archers +1/+2 bonus attack, and chain lightning affect+1 target/+2
