Mu Lung Dojo, no gloves?

Sure it does. You're speaking to a guy who used a 6% total damage 113 att cannon from 110-18x. Higher attack cannons made my range go way down.

Possibility it might not work for the gloves, but the only reason i can see for why is because of "special potential", since it's new.

No, it doesn't.
You're speaking to a gal who cubed her sword from 6% attack to 9% total damage, a few weeks ago. My range went down 6%. My actual damage went up. I hit above my nominal damage max, using regular attack with no buffs.
