You dont get crit bonus from c1 anymore.
And well full draw is important for an archer if youre only an archer and you for example go to the dungeon at lvl 50. You link mobs together, they share damage - helps a lot.
I didnt make a ranger yet so dont want to comment on those skills, but dont use barrage as single target damage unless you mean on bosses. Neither barrage nor anchoring is to be used that way if you want to stay efficient and not chug SP pots like a madman.
You will wish you went sapper when you get to chapel and do it solo hahaha ^^ that place without a group is terrifying. There are rooms where theres easily 60+ mobs. Not big rooms either, good grinding place if you got the aoe dmg but dont fret ranger will provide that too.
Only way to be truly mobile right now as an archer is SR but I didnt see the need for it yet.
Too many levels in oblique and you have to mob more to make use of the aoe properly. Save up exp cards for the times you need SP / HP badly. Then chug couple of them and poof level. Also dont be afraid of chugging pots, I do that.
