I'm basing it off experience. Sure if you have a very dependable strong burst comp go ahead and go Archer. But if you depend on whittling people down 200 potency which rarely comes by to use at a long CD doesn't serve it's purpose. Fracture sure it is strong when paired but don't forget that with every Heavy shot you don't use there is lesser chance to get Straight shot proc.
Next comes the biggest problem that is 20 + 1 Dex cause of Party bonus and the amount of Vit loss. They have so little HP that they get rolled over too quick. Sure utility side you're strong but if you don't start killing things or pressure you are going to lose no doubt about that. Also starting off the game with Paeon sprint and turn it off on engagement you can save that invigorate on everyone on your party.
