Mind Games Mandatory for pvp?

Looking to do some pvp, but my primary function is raid and M+…

I want to be kyrian for PVE… for disc/holy.

is mind games mandatory to get to high ratings. did 1950ish in 3’s season one SL - want to push higher this season in my spare time.

Dont know but the new Leggo with the Soulbind will give a pretty nice boost of Crit for PvP (50% max for 10sec) if u combine it well with Nadjia 20% crit buff gonna be really strong with the Ghost talent
