Oh, thanks Karbuncle, reminded me of a few other points;

No shadow system, please. Or if there is some shadow system, don't freaking make the shadow so stupidly and ridiculously rare. Also, it sounds like the battles may have some sort of Battleground buff status (I know I'm using the wrong term but I can't think of the right one... Conflict? Think that's Ballista, but hopefully you know what I'm talking about). If this is true, don't give the enemies a knockback effect, or if you do, ensure that it won't immediately knock you out of the radius you're allowed to stay in, prematurely ending the fight, that was just stupid. Also, if it has the ability to basically one hit kill upon pop, give it alliance hate or something... Yilgeban was a total douche, sorry.
