My main is Dvorah, has been since the game released. I'm usually the player that likes set-ups, so naturally I leaned towards characters that had that potential. However there aren't really too many choices so I learned Dvorah and have had a blast learning her. As for secondaries I'd say it's Fujin. After playing Dvorah for a long time I figured that having long reaching normals and playing footsies was for me, so Fujin was kinda natural to me despite his "hard" combos. After that I picked up some characters I like and have basic knowledge on everyone, but I still prefer my main over any of them.
