I was curious what the primalist focus would look like?

Would they be able to equip rogue and warrior essenses?

If so can they use
2 Ghar upgraded Crit Power essenses,
2 Ghar normal CP essenses, and
2 Ghar attack power essenses?

And then they would not have to get them from other sources like everyone else?

Maybe it is too late for this, but have you thought about having the primalist Main Stat use Dex and off stat use Wisdom.

Then we would not have the same conflict with the gear that we do now. And maybe you could have all lvl 64 or less gear have a free upgrade path to switch strength -> wisdom or something so that you don't have to create new gear.
