At what point are defense series tips worn beyond usefulness?

I've been running a lot of tests using a WD tip on my practice dummy and noticed its worn to where it's starting to move like a WB tip with better LAD, is that sorta the point where its not really useful on stamina combos or is it still good?
Ooh, I'm not sure. It's obvious that it's too worn when it starts moving like an attack-type, but this isn't quite the same. If it's slightly mobile like WB, then it should be okay. It might be a little worse stamina-wise, but it still has good LAD.
worn tip = bad but good attack type. which in my opinion is good because attack is my fav type

pretty sure if a defense tip is worn enough that it acts like an attack type its not legal
