Best merc armor?

Hello i am wondering what is best A2 merc armor. Since almost every armor is 5/6k def excluding treachery unfortunetly. Which armor is most OP and universal?
6k forti
3k coh
2k treachery
Eth upped GA dont know def
? If I miss any lmk and plz describe why i should choose it.

TY

 

What is the main char? The rest of equip?

Without knowing any better, I would go with forti.

 

Probably Hammer//Nova Sorc//Bowazon//javazon/chars ^^^

 

Well, for hammer and bowazon i would probably focus on something that will speed up your boss killing, so i would go for build that can give me enough ias and CB to do the job.
With the rest, it doesnt really matter

 

Either forty or duress depends on what you want

 

forti or duress, depends on CB on rest of gear ))

edit: or Rattlecage for 25% CB ✌️
