While relying on mages' revival power is a good teamwork skill, archers really need to be able to dish out serious damage and survive. This especially comes into play when constantly using xp pots to attain level 56. Dying isn't bad, but if it costs the team a lot, then it could be a problem.

Now, regen is good, and you can easily achieve very high regen while keeping high damage output. My suggestion would be to go for a Sewer King bow with Underling Cap and Leather. This will give a pure dex bird a total 9 H/s and 12 M/s, as well as 26~ crit (depends on which ring you use) and fairly high damage. I used this for a while before giving up regen for some armor and crit.
