Idea!

Continuing the discussion below on the proposed new unit types, I came up with a brilliant idea to eliminate the problems with ranged units: Simply reduce the attacker's strength based on the distance of the attack

Let d = the distance from the attacking unit's square to the target unit's square. Then:

• If d < 2, no effect
  
• If d = 2, attack strength is reduced to 85% of normal value
  
• If d = 3, attack strength is reduced to 70% of normal value
  
• If d = 4, attack strength is reduced to 55% of normal value
  
• If d > 4, attack strength is reduced to 40% of normal value
  

This system (or something similar) would probably make the units proposed below work without turtling becoming a problem. Comments?
