Darian should have won this vote, IMO. Second one TomMyYY and third Teeth.
As has been mentioned, while TomMyYY is far from your average cav player on horseback, neither is he on foot with the same build. AFAIK, he has very low IF and 7 athletics, 5-6 powerstrike(possibly lower) which is fairly gimped for an infantry-centric perspective. In this state, Teeth has more than enough of a chance. I still believe Teeth can contend for the 2nd place for the Dutch player base even if TomMyYY had a non-gimped infantry build. Teeth, to my attention, began improving rapidly just recently(4-5 months). It would be my guess that he is still in the process of fine tuning and mastering his playstyle.
However, Darian is playing in one division above both Teeth and TomMyYY(not by much, but noticably so). He should stick to what he knows and a build that is balanced and he will prove himself in many people's eyes, not just folks who duel a lot.
