I concur with Nex. I use TK classes a lot (starting work on my third to make a SG, getting Ranker points with my second, and my first is a 91/50/50 Linker). They do need a skill that can just be activated (without being a ranker). And if you are gonna use Axe Kick, get a Masquerade Lion Mask. +2 Dex, +2 Atk per refine, and +1% chance to stun per refine, only for TK classes. That's an extra chance to stun your opponent.
For the most part though, use Whirlwind Kick and Counter Kick. Whirlwind for mobs, Counter for serious hunting (or MVPing if you are strong enough). And abuse that Whirlwind kick in Orcs Dungeon with Warm Wind 7 on. If you are truly new to the server, find a Picky card and stick that on your armor. +1 str, +10 Atk.
