I have been playing on TK since the beggining till lvl 70 and I can tell you some points:
1. For AoEPvE is an amazing class, bcz the life cubic and the high WIT status helps a lot on hp potions crits and BS's MP saving.
2. Solo PvE is shit bcz u dont have enough dmg, even with full str.
3. PvP is funny and at same time, boring. Bcz u dont die for any warrior/rogue/mages* (if u know how to pvp against them or if they were fingerless)*, for the simple reason that they reach on 0 mp before u die. And Attractive Cubic piss them off as hell with his 100% root. The boring part is bcz u dont have dmg enough to kill them.
4. Mass PvP u will be the last man standing, u already can imagine how boring can it be. The max u can do is Entangle/Aggro/Judgement some enemies. Ur cubic wont have time to cast root or smth.
5. I gave up on TK bcz im not masoquist.
