lol, calm down. Wizard has a lower def but their magic makes up for the low def. They also got ranged attacks which makes their class deadly. Compared to the bladers they're strength is a little lower then the warrior and their def is too low compared to the warrior.Don't get me wrong Bladers are good as hell in PVE because if u build them right no mob can touch them.
Yeah range is better because all u need to do is keep distance between u and your opponent which can easily be obtained by using the dash skill. Basically if u don't have range attacks u lose simple as that. Wizards and Force Archers have the advantage because they can damage their opponent before close range can even touch them.
Blader's Bm2 also rocks. Since they have a chance to deal critical to the opponent killing them instantly. I did it twice just yesterday (^_^)
Can I ask your character name and channel? Mine is Zongying Server: Mercury (fellow noobie) ? (0_0)
