So whats wrong with archery:
1. The Attack speed animation is just too low.
2. Archery is feat intensive to start, and even more feat intensive to do resonable damage.
2hf - PA and IC and you are cool
2wf - PA, IC, 3x 2wf and you are cool
Archery - Bow strenght, PBS, RS, MS, PS, IPS, IC and you are cool for 20 sec.
3. Slaying arrow is overpowered and is holding whole archery back. This also result that for archer build you need to have AA.
4. You cant combine class PrE and favorite class PrE so best archers are anything but Rangers.
4.1 The most viable archer builds are very complicated one like monkchares or HE Angels.
4.2 Generally there should be a switch when you can build Ranger AA, or DS elf or not. Or as well barbarian and Kensai (without AA) and all of them will be equal effective. As well as you can give a bow to cleric/bard/rogue and it will do same job as Greatsword with similar (minimal) feat investment.
5. Ranger Mastery is overpowered and is holding both Rangers and Archery back.
So here is how to fix archery:
I. Remove bow strenght from the game and never look back.
Str mod to bow dmg is granted as long as you are proficient with the bow.
This feat serves no purpose other than making life of no casters miserable nad forcing all archer builds to pay "feat tax" for no reason.
Rangers receive PBS as the lv1 feat (or whatever else).
Gnolish warbow gains: Feat: Bow prof; Feat: Precise SHot; and Shocking Burst enhancement.
I.1 To keep things equal for all:
As soon as you are proficient with xbow you benefit from 1/2 of dex mod to dmg. Any class feature just change the mod to other(higher) value. (do not stack). So arties benefit just from Int mod, but you can also give a xbow to your bard and pew pew a little as long as you have some dex. Even better if you buy Repeater feat.
II. Increase the general bow (and throwing) attack speed by 1% per BAB. (up to +25% with full BAB with epic levels)
III. Change Archer Focus to:
For each 3 sec of staying in place gain the stack up to 3 stacks. Each stack increase physical damage dealed with a bow by 10%. (up to 30%)
Archery Focus is a passive and stacks with everything. Works with throwing and xbows.
IV. CHange rapid shot to:
Stance: -2 to hit.
If you stay still (1 sec to activate) you shot a bonus arrow with a chance of Dex value. So 50Dex = 50% for bonus arrow. This effect do not stack with manyshot and 10k stars. It dosnt matter if stacks with IPS or not.
This dont work with xbows. So they may skip this feat completly - free cheers for removing feat . taxes.
Note: Static Archer?
Yes, the big advantage of ranged characters (including casters) is the kitting ability. This is the reason why its ok that archers deal less damage. However as soon as archer resign from kitting (or stays in PBS range) he should take part of dps back.
V: Shot and RUn
Also provides 4% of Dodge as long as you wield ranged weapon of any type. (may be throwing or xbow) Nobody will use it anyway, but at least there will be the option.
VI: Rangers lose Ranged Mastery.
Rangers receive real capstone: +2 Dex, 5exeptional elemental resist of all type (or 10% elemental absorbtion) and vorpal strike against FE.
Nothing less will keep me from splashing with rogue. ;-)
Note: This just a single change from many which must be done with Rangers.
Problem with Monkchers/HE Angels being better than good old Ranger Pewpewer isnt that Monkchers/10kStars are overpowered. But that Ranger is such a poor class with borked class mechanic, limited spell selecion, no party utylity, and low situacional dps.
Taking more than 6 levels of ranger is just steady lowering your dps.
VII. Arcane Archer
Terror and Slaying arrows are merged. And now are on demand clikie with long cooldown and some SP cost. (like 30SP per use) (lv20 ability)
True Strike gains longer cooldown, but is now true strike. (natural 20 on wish)
AA can choose which imbue shoot from 4 elements and force (with lesser die)
Bard splash AA can shot sonic arrows. Divine splash can shoot light. PM splash can shoot negative energy.
Each tier of PrE provides bonus enhancement to imbues.
AAI +1d6 of element (or 1d4 force)
AAII + Blast
AAIII + Burst
AA can additionally on demand shot with explosive arrows (fireball like effect). for 1d6/lv (or 1d4 for force).
Terror/ Slaying, True, Explosive shots all cost some small amount of SP. (like 10-30)
VIII. You can combine with your race PrE and any other class PrE. So yes for Elven AA deepwood sniper.
IX. You can stun with arrows. *using blunt heads*
X. New Feat: Pin, single victim is tangled in place and immobilized can still cast or autoattack.
XI. New Feat: Volley - shoot 5 arrows in cone in front of you. Stacks with IPS. Do not grant hitting all targets in cone. Just one on projectives trajectory.
XII. New Feat: Barrage
In circle around target area all objects are hit with arrows from the sky.
Pin, Volley, Barrage is autogranted to Deepwood sniper at various levels.
Could be however pick by any other class with some sensible preq. (like PBS + weapon focus)
XIII. Bowbarians return to the glory.
Frenzied Berserker works with Bows and Throwing weapons.
XIV. Marksmen of the Chalice are founded!
Paladin abilities works with bows.
XV. Epic Feat: Bulls eye/Overhelming shot/Fancy Name Here
Preq: Dex 23, PBS, Weapon Focus: Ranged, PS, epic levels
Effect: Crits 19-20/+1 on ranged weapons.
And thats it.
