The reason I like a 2H sword

I have had long DFO career, and throughout my DFO career, I have stick to use a 2H sword. Moreover, I like it a lot and tend to use it until the last day I am a player in DFO. I am pretty good at my weapons; of course there is still some room for my improvement. Throughout those years, I find that it seems all successful PvPers are polearm users thought. I have not seen a good PVP video cooperate with some one to use a sword yet. Due to this, there are some inquiries to those using 2H swords in my mind. I would like to share them with all of you. The first one is: how successful are you at it? The second one is: have you thought about switching to Polearm? The last one is: why did you or did not you switch to Polearm.
