GT: Guardian Tortoise
As for playing effectively, simply put: if you hate charging MP, you probably shouldn't be playing a class designed with the ability to charge. If it's a question of playstyle, you can get away with minimizing it, but to use your class effectively it's best if you don't have issues with the basic aspects of the class.
