Is there a good archer build in POE? Not the strange matrix-style DH of D3 but a true archer\ranger.
Yes. Split Arrow, Tornado Shot, and Rain of Arrows are the strongest (possibly not in that order, but that is fun to play order). If you want a good starting guide, look up Neversink's Tornado shot build (it works for split arrow as well).
If anyone is playing Warbands and wants to team up, let me know. I just hit 70 ("rushing" Atziri, really) on a Ranger and am doing great (Frenzy charges and Blood Rage are OP!).
So, if your build is borked, is there no re-spec?
Planning a build can be nice and all, but no re-spec on a grid you're obviously never intended to fill out is pretty lousy.
Essentially, not without spending a lot of currency. As said above, you get 18 respec points simply for progressing through the difficulties, but if you need more than that, you're going to have to buy Orbs of Regret, which get fairly expensive.
Some easy pointers though: prioritize defense (HP, resistances, etc). Life is better than energy shield; you can regen life completely with flasks, with ES, not to so much. Think about the damage nodes you are taking; if a cluster of damage will give you like 40% increased, but costs 5 points, there could be a damage cluster along your path that gives the same and only takes 4 points. Jewel sockets are great; if they are 1 to 2 points invested along your build path, get them. Poebuilder.com is a great resource for researching your pathing. Also, move speed is more than a quality of life improvement. Being able to dodge ground based mechanics and move away from enemies is big.
Oh, and your first character will be awful. Just accept that and try out skills you like.
