My personal thoughts and observations:
1) Horses still give too much points. I don't like it because in any possible way horsemen should give more points than a horse. It's the same as if it would give points for breaking a shield more than for killing a shielder. I like the idea of giving points for damage to horses but it should be lowered.
2) Proximity based points. As far as I can understand it gives points in 3m radius of that who was attacked not who dealt damage. If it is so - then it makes no sense at all. I can just do nothing and stand close to enemies who got shot by ranged and get points. You should make it so that points are given to those who are in 3m radius of that who dealt damage. This will encourage archers to stay closer and give them some bonuses on strat while standing in formation. This will also encourage shielders and pikemen to protect archers against enemies. Charging horde has nothing common to teamplay, remember this.
3) Ranged is inferior scorewise. I understand that ranged should be given a smaller amount of points but archers suffer from this new score system, especially on open field as their team charges and they have only 2 options - follow the crowd or die from cav because nobody stays to defend them. The situation is even worse for crossbowmen (probably the worst class scorewise atm) since DPM of crossbowman is much lower than archer and drastically lower than melee player. According to the fact that you can make only 6 shots per minute with 180 wpf using your Arbalest makes it sad. The real situation demands movement and aiming from crossbowmen (amount of open maps is frustrating, there is only 1 city map without huge open spaces - Riot in Swadian city) and I get most of my points by killing player in melee fights. So it's impossible in most cases to make even these 6 shots.
4) Points for kills. Yes, I understand the statement that damage is everything, kills are nothing. But I kindly disagree. I'll mention some situations where damage means nothing and kills mean everything.
1. Horse Archer or Horse Crossbowman riding around and killing players. Damage doesn't mean anything at all since it doesn't affect him. He will do the same thing in the same way until he gets killed. And it's kind of frustrating when I'm making a perfect shot killing a rider in 50 meters who killed 6 our players and I get only a couple of points.
2. Hero who is killing my teammates all around. This is the most common case: a hero with great fighting skills eliminates the half of my team, he received a random ranged damage from my teammates so he has low HP but keeps killing my teammates one by one. I make a headshot and take almost nothing.
3. Rider who got his horse damaged to 1 HP but still he can ride, he will stop and change his horse to the one which has full hp.
I think this system needs some kind of tweaking.
