If i remember correctly, when your in a level capped zone you dont get Limit Points even if you were on limit points before entering, you get experience points (Not sure how this works if your capped exp)
So they wouldnt be earning limit points they would be getting experience points, this would explain why Ruffy wasnt sure if he was on exp/limit because he was probably getting exp.
If im wrong about this then my bad.
Edit: Please tell me how i should have asked in order to explain myself correctly, what did i do wrong? I told them my pt was getting double my exp, we all had signet were all normally 75, we werent sure if we were on limit or exp, no one was using a ring (He kept asking me if i was sure of this one).
My point is this shouldnt happen (In my opinion), and if its meant to happen this way, the GM should know this, or am i wrong?
