Ya know, there are anti-loose USB cable clips that keep said cables perfectly still on the DS4. Last one I bought was 3 years ago and I don't see them on amazon atm, but definitely keep a look out.
I noticed that your username was green in these matches, was that because of an editing decision, or were you playing on Stylish mode? Actually, I'm not even certain if you can pick Stylish when online, I'm nowhere near good enough to be comfortable going online in BBCF. BBTAG is a slightly different story however. But only slightly. I'm not good at utilizing most of the partner mechanics. Gotta say though, that double perfect on the Susano at the end there, was beautiful
Kozen you should really try to play the BBTAG community build. They did a lot of characters justice and I feel like you and your gang of friends will enjoy it again.
