please help my Earth Iop

i want to try earth Iop and with air in Gutting gust but my friend said i should leveling the Judgement in fire element too and so i can use super Iop punch in pvp to gap closer. what do you guys think?
for me it sound good but i don't know will it work in the end.
Judgement use the same AP and MP as Charge too.

and how many turns Judgement will remove range from target?
will it stack?
is it wroth for Earth Iop in both pve and pvp?

Here is my build. it's focus on Crit and block.

thanks
