As a main archer player, I personally go for long bow and extra arrows, seeing as the other perks are rather not worth picking over these. The two-handed axe is nice, but it's really impractical in terms of utility. I'd rather have a default weapon and pick up an enemy shield to have some more protection than go shock infantry when I run out of arrows or need to engage in melee.
I would give it a better default weapon, perhaps a short sword. The hatchet is really bad.
This class is pretty nice, you can go full damage with the longbow and snipe from afar or take the melee weapons and use the short bow to support your allies close up. I've heard it's going to get the Fiann's default 2h as a perk next patch, I would probably advise against that but we will see won't we.
