Wow, lots of comments here about archery! Where to begin/
@DWSmiley: 60 damage a hit is decent, and with the right gear you do have a decent attack rate. But any warrior archer who takes two feats - Melee Archer + Aim & uses the same gear will be almost as good as your full dedicated archer for auto attacks. So he does 50 points vs your 60.
Plus my mage was auto attacking with his staff late game for 70 to 80 points. Through in some hexes and he was hitting over a 100. A mages auto attack beats an archer. Not good.
@tbastion: I have noticed that whoever damages a target first seems to hold the most threat. It takes a lot of damage to have the monster switch targets. Probably what you are seeing since the archer will usually get the first shot in. Noticed this a lot when playing a mage and started opening with a fireball.
@soteria: There are easier ways to compare rather then playing a full game. Simply save the game before a zone and then play it out as one sub-class. Then reload and respec into a different subclass and play the zone again. I am a chronic restarter and I did that a lot in the begining. LOL, probably why it took me so long to beat the game. But anyways, I defintely noticed that the Warrior Archer sub class was a lot more difficult then any other warrior spec. It was REALLY noticable in the low levels, in the areas post Lothering. Looking at total party damage is a poor indicator because AoS adds heaps of damage to the totals against some scrub with 100 health.
@mosspit: What can I say, I hardly every disagree with you and this time is no different!

Why Archery sucks to me:
1. Draw DMG from the average of two stats - Dex and Str. Since the stats are average your damage will always be 1/2 of a character using a sword. They tried to fix this with the dex hotfix, but it made the game really hard and they scrapped it
2. SLLLOOWWW animations on special attacks. Auto attack = boring in my book
3. No runes/poisons or really good bows: Really you can get Farsong right out of Lothering and that is it. best weapon in the game for you
4. No deathblows: Come on - add some cool animations where your archer shots three or four arrows into an Orges head. Make it interesting. Instead I want anyone BUT my archer to make the final kill
