Running is harder, but very possible. It's also very easy to jump out of the dojo when there's 90 frames left

Also Rk-mma is one of the most opener based mods in the game

as long as you're not getting dq'd by the opener( if you are then you got problems you got to work on). your chances of winning is still pretty high. compared to lenshu a good opener and you're at a massive disadvantage compared to the opponent. they can easily point hold for the entire game. i disagree with rk-mma being a heavy opener mod. matches are rarely decided by the opener.

I believe aikidobigdojo is the most competitive mod because it is a mod that does not easily allow a player of a higher skill level to completely shut down their opponent. Even with an advantage a player must be an active participant in the match or they might find themselves in an unfavorable situation. This allows for not easy comebacks, but easier and preventable comebacks which make it such an interesting mod to watch, and how interesting and entertaining a match is to watch definitely plays a role in how competitive it is.
