sumore, any variant made by Odlov and not the weird bastardisation that seems to be in circulation.
Battledome, another Odlov mod but it's a very nice change from wushu with no dq, could be great in beginner rooms and advanced rooms alike.
Aikido7, much more grappling orientated than other aikido variants - ABD is just not grappling at all so it's disappointing to see it in grappling servers. More sw is always good too.
Rk and lenshu are completely different with completely different metagames to say they are the same and should be treated as such is dumb.
Striking reborn mods are always nice too, they have a point system that doesn't reward rush kicks and actually makes sense competitively. GMs said it was confusing but is anything more confusing than the current system?
