How fun is DFO?

I know its all about doing dungeons, but how fun is it in terms of pvp? I'm thinking of starting this game but only cause it has a pvp system. Anyone play DFO that has played WoW? I used to play WoW when I was in the states but now i cant cuz I moved to korea, and I used to LOVE the WoW pvp system. Like how each class has a skill that makes them useful/counter another class's skill, like Arena in WoW would actually take knowledge in your class and skill (Silencing spells, Using cool downs wisely, CC (Crowd control) one person while taking out the other). Is the pvp system in DFO similar to WoW where you actually do all these things to prevail, or is it more of like a beat em up kinda thing, like Street Fighter?
