I don’t know if this has been suggested before or not, but here it is.
When in combat we have 3 rows in which players or troops can be in. I’d suggest giving the people in the back 2 rows a damage reduction bonus if there are people in the rows in front of them.
So if there was a mage in the back row, an archer in the center, and a knight in the front, the mage could take 90% damage, the archer would take 95%, and the knight would take 100% from any attacks. Lets say the knight died, the archer then would take 100% of the damage from attacks directed at him and the mage would take 95%.
Right now, there is no real reason to have the rows, unless you are fighting a group of knights. And even then, it’s not that effective of a strategy. Most of the time, it’s overwhelming force or just dumb luck that wins the battles atm.
