im not to sure about how the spell system is going to work but from what i understand they are going ot have a party system where we can gank monster togeather and yes you will be able to shoot arrows at them but i think ranged skill is slow fire one sort of thing. They will probably have it set where the amount of damage delt to the monster affects how much exp you get from it and stuff like that, there are plenty of mmorpgs already out there that have really good battle systems to draw ideas from so dont worry it will be a good system im sure of it. :]
