i'd say any of the thief classes

I really enjoy classes that are close range and in your face, like Shads, Dual Blades, and Buccs, but I enjoy Dual Blades in particular because they hit with very fast close range attacks with tons of lines of damage, even if the damage% on each line isnt anything too crazy, but thats just me. Oh, and Asura says hi. We also get a small revamp soon that decreases the delay on some of our main attacking skills, plus some minor damage boosts from hidden blade and flash bang. Speaking of Cannoneers, they're are very fun imho too if you like the "mighty glacier" style of gameplay; they're hardy, a bit slow on attacking and their mobility can be a bit tricky getting used too, but they have some of the more unique skills out of the explorer branch, and buckshot and rolling rainbow seem like really fun hyper skills.

Shads are very fun, but i am obligated to recommend my class, since we are going to be revamped soon
