The question about Ench.gemming.
I know that BiS usual gems for us is: +32AP, +16Hit, +16Exp.
At the moment my Crit EP got the biggest EP volume from all base stats and I know that I need more Crit.
When I start thinking about increasing my Crit by gemming I'm aware to use pure Crit/Agi gems because almost all know that Ench MUST use only gems above (except blue, violet, orange). Does anyone use pure crit/agi gems after they capped hit/exp?
