my Feedback to the game on PVE is very simple give special qualities to weapons and armor so everyone can have better pve experience, not just used the BiS stuff give the player the decision to a why use a different weapon on a different region not only more monster damage 

for example if you run offin then you have better damage on (mirumok manshaums gyfin), dragon slayer could have more damge on lizards (saunils dragons etc) ,muskans you take less dmg on muskan etc i think that would be better for the game market it would influence in a positive way cause you are giving the tools for the player to choose something different 
Dragon slayer has 7 damge against all specie but can get special buff on Dragon like creatures 
Offin can have a similar trade with kama mobs 
kzarka with serendia mobs etc 

that is my feedback to the game
