Wellll...check out CK. It's almost word for word. Mechanics are exactly the same.
As for archery: it's actually a LOT easier to get it to work than melee. I'll link you to my level 10 one here in a second...or I would if MW wasn't kablooy. I've got...Dark Stalker, PBS, MS (from ranger), RS (from ranger), Precise Shot, GMS, Swift Hunter, and one other feat (I've got two flaws). I can't think of what it is right now, I don't think it's.....Fly-By Attack, that's what it is. With your four levels and no buy off in effect, you can have all of these for the low, low price of one flaw. It's all you need....other than the warlock dip for infinite hiding, but that can come later, or you can have a cleric cast Deeper Darkness on an object that you can hide (thus blocking LoE...and thus blocking the darkness) and tie to a 10' pole strapped to you or something so they can't target just the center of the darkness and have a 50% chance of hitting you.
