well he do ask for wich class to make as his first class
i would say turtle easy pve farming and pvp
karma is soo say usefull in speed party cause of skill lock (debuff) and attack speed (buff) - karma pvp is based of timing on using skill and perfection also the class is known as the best 1 v 1 class soo yeah you need to wait with this class until you become rich ingame to buy good stuff for this class tho
but yeah i rather go for turtle for easy pve farming solo after all you can enjoy your cancer kamehameha skill
