Currently the main 1v1 classes are Sin, Mage/Wizard and Veno.Seeker has become popular due to the recent patches as well.
Seeker is best all around, its better in mass than sin but still very good in 1vs1.Mystic is also viable but only if you want to support during RPK, its still a good 1vs1 class.
I love seans cum
What the fak dude! Only useful thing they can do in mass pk is to make enemy lag
Make wiz... Get x2 Ct on each piece of gear.., Get good def gear... Go in mass do ice prison and spam fire combo... After that you will be known by all because thats how wiz is... You spam fire combo and you are considered good
I need to make a mg.
