Hey i see most people who play toribash are good at SP but then when i do it i get no motivation and whenever i make like 7 decaps it looks terrible. Is there a certain way to get good at Single Player? Also i am very good at MP.

Just practice. Learn what every joint do, and think on how to use it, get inspire by your imagination (like I want to do a backflip decap) and practice again.

I know what every joint does, im just retarted at making combinations at the top of my head. Or if i do it has bad style.

Well, if you always hold all it'll look bad, relaxing some joints will help to make your moves look better.

I don't stiff fight lmao

SP requires more precision and creativity than MP since you're the only one doing anything. If you like MP better, don't frustrate yourself on killing uke ;o

If you want to be good at SP just practice A LOT. That's the only way to do it.

If you don't have patience however, just stick to MP.

Its practice thatsall it takes.

Practice and inspiration. Practise a lot to learn what different joints do then watch other people's replays or a tb vid to get inspiration of what to do

I'm a replay maker, and from my point of view , you can't call someone who uses a lot of held joints stiff.
And you can't call someone who relaxes most of his joints a pro.
Stiff = someone who uses contract / extend only.
Here are two examples of hold/relax cool replays.
NutHug's replay , that pose was hold all. Is it stiff / not cool ? I doubt.

Ruki's replay , the movements were almost relaxed. Are the movements better than a combination of hold / relax ? No.
