Combat and classes seem really fun and other than the usual tweeking with balance issues, here's my biggest concern. The Maps seem too static, not enough going on around you. When you're pushing forward with your troops, there should be check points or something where you get to batter the door down, or catapult something. More NPC crap happening that changes the war zone or gives more of that "In the Fray" feeling while you're in there. War is a mess, it should feel that way all the time. More environment that effects you as a player would be cool. Fire Arrows that kill everybody if you don't get out of it. Boiling oil being poured on you as you are battering the door down. This creates a hot spot to get up there and take out the NPS who are doing it or kill the archers shooting at you and your troops. This seems like a better motivation for control points than just a base that changes color and gives you points. There needs to be more purpose and war driving the control points instead of just a control area. I really like the idea of bringing in NPC interaction in the game. like a catapult hitting the wall and exploding knocking people including the players around.
Don't spend so much time on the classes and characters that you forget about the play-ability of the game. This is where a lot of PVP type games drop the ball. They make these cool classes and abilities, but the game gets boring real fast because they just throw you in the same old PVP Arena every time. You guys have the chance to do something innovative and amazing with the base you have started. Keep the battlefield changing and moving and motivate the battle field with cool checkpoints and amazing rewards as you keep pressing forward. Arrows will fly, walls will come down, Neither Heaven nor Hell will stop me from my fate.
