i'll mention my case with regards to striking as i think it should be a huge part of the game.

imo there shouldn't be 1 mod only for striking or even 2..but 3

50tf/30tf/40tf with their corresponding gravity are marquee settings for striking players. The meta is the same which is striking, but they offer a great variety. You can't replace one for the other IMO. I'd be glad for you to argue my point though!

lenshu3ng: would suggest no modifications there

rk-mma: would suggest a slightly larger dojo. preferably same as lenshu3ng

you see rk has weaker gravity than lenshu3ng, so it makes total sense that it has same dojo size! would love to see the thoughts of striking players here too.

wushu: use wushu3dome or wushu3box. They are BOTH good enough to be considered competitive. You just can't leave wushu out specially when there is a competitive mod for it but people are disagreeing on which mod to use.

grappling mods..I'm sure plenty other people know about it more than I do.

kicking mod, idk why you're considering it a meta. erthtk/tk is just a striking mod with different tf, don't you agree?

i would have only two mod types: striking/grappling

striking: wushu3box/wushu3dome rk-mma(modified maybe) lenshu3ng erthtkv2
grappling: IDK

im gonna have to disagree

this may be a bad analogy but how i like to think of it is that, erthtk to tk is sort of like lenshu3ng to wushu. there is the same core play type that comes to mind since they're mods of similar types.
but when it comes to the technicals it isn't quite the same (although it might not be as drastic as the striking mods.)

just like hax said before
for example in tk a block that is not well placed or brute forced their way through will result in a arm dm of somekind.

meanwhile in erthtk, the higher dm threshold prevents these as well as the seemingly random dm's that occur when you move a bruised joint and it just falls off (to an extent.)
also the higher gravity and out of ring dojo dq in erthtk prevents wrist break runners from floating away once they have a mere 1k point lead

Yeah, I agree with all you said. They're not the same, but what I'm feeling from you and everyone I've talked about is that erthtkv2 is an improved/fair/more competitive version of TK. So it makes sense to use only erthtkv2.

Let's take the striking mods:

wushu: there wushu3, wushu3box, brushu, wushu_2015, wushu

they all change a bit of the technicalities. in wushu it is opener based, in brushu you have these long matches with higher thresholds which allows more movement. there is wushu3box which includes the jumping off a box and prevents running. they all change the technicalities, but the core is the same it is still WUSHU. and you still have to pick one of these for the competitive scene.

rk, and lenshu are TOTALLY different! totally diff gravity and tf. it's a huge difference!

hope you agree with me there
