It's kind of weird server , becouse of those SUB classes.
Everyone have Spellsinger , Titan , Bishop .
I can explain you why . Spellsinger becouse of casting speed and mass spell , Titan becouse they need more HP ( idi¤ts ) and Bishop becouse of heal . So you can be whatever you want and you wont kill it .
It's like this -> F1 = Aura Flare | F2 = Greater Battle Heal | F3 = Mana Potion
And thats all ... you cant kill him becouse of cast.speed >_<
