Doa4.1 made some minor tweaks to the juggle system, lessening the gravity so that certain juggles and air throws can work properly. This update also fixed some of the ground game issues(increasing the frames to use down attacks and down throws. The Negative aspect of this update was some of the character tweaking which was used to balance the game. Some players see the majority of these tweaks as a bad thing. Yes the game is more balanced, however, this balance removed many of the loved aspects of the game. Such as wall 2-in-1's, standard 2-in-1's and other like combos. Otherwise Doa4.1 is a fairly decent fighter amongst it contemporaries.
