The reason I said stack is worse than mixing stuff is because I believe (and I already covered it) that similar buff and debuff are treated as additive much like buff.. Therefore 50% buster down + 50% buster up is counted as 100% buster up.. at least that's what I observe from stacking atk up + def down on enemy. Thus Buster down should be treated as just another buster up and from enemy with Arts resist down I realized that it also carried into real card performance (e.g you get more NP gain from enemy with Arts resist down)

Also by order of math calculation NP damage up are calculated last therefore it has the biggest multiplier effect, however as you said it doesn't really matter when the parent damage are small.. I haven't cross checked it with Kyte formula but I'm sure that the order of calculation is 1.) special damage up 2.) Atk up + Def down 3.) Card Performance Multiplier 4.) Np damage multiplier, 5.) Attribute modifier.

In short NP damage up are 1 rank higher than performance up and it is a precious skill if you already have the previous 3 above it's rank.. and the highest multiplier of them all is ofc Crit damage up but that's pretty irellevant for NP..
