Glaive help

Hey. Im wondering what i should do with my pure str glaive build. My skills at the moment are 48 heukusal fire lightening. and 28 cold and im at lvl 53.
I cant decide if I should change lightening to cold. I keep seeing people saying to chose cold over light. but idk if it is worth changing my build. What are your guys opinion on this?

My build is Cold 38, light 72 fire 110 heuk 110, works pretty well for me :]
Since you're pure str you don't need to pay that much attention on cold.
Yet, this is just my opinion.

Why did you choose to go with 38 cold?
