Tips
* Every class recieves something special when they change there job at level 60. Rangers get HIGH Block Rate.
Its recomended to go Full Dex Aoe because you will block alot and your damage will be very nice.
* Aoe Sequence: Ice Arrow,Flame Arrow, Arrow Rain, Flame Arrow, Ice Arrow.
This is the sequence of aoes which i used, but its up to you. Do Whatever you like best :D!
* Jewls - Use Mp Necklace, Areks, And Plugs.

I Hope this is helpful to everyone.
