The duel system is rly good to start of with. It works pretty well. It adds a purpose to dueling, a goal. (I hope u know what i mean)
The rly good high ranks cant just feed on peasants, hell we cant even feed that much on medium fighters. So it forces u to fight players at ur ranking/points to get somewhere. Which is rly great. Obviously u can try and find a bad player with 50 points lower than u, but he will only give u 1. The system works great here aswell, because if u lose once. U will lose alot of points, probably around 17.
I have 416 points atm, and i am currently number 1. But it is not easy to stay up here, i am for sure gonna lose it tomorrow. Since u have to play perfect to stay up here.
So overall i rly like the point/ranking system. Its also a sweet detail that its added on ur character on c-rpg.net. But i would like 1 thing, being able to choose between ranked and unranked duels.
