hello okuno, these are my suggestions:
Anky (pve):
-Strength, armor, endurance and agility/stability (only if you attack rex)
(pvp):
-They may be the same as the previous ones, but try to use a heat implant instead of armor.
Para (pve):
-Strengh, endurance,agility and vitality/stability (only if you attack rex)
(pvp):
-vitality, heat, stability and armor or agility
-Agility, strength, heat and armor
