Revised Suggestion for clarity and ease if implementation. Give Archer style rangers ability to choose feats other than rapid shot and many shot (because they have them already), without removing those options for twf style rangers who want them, and beef up the kit to make it more worth the loss of spells
First if all
please make Hunter Trapping stop breaking stealth.
Then, suggest editing kit as below:
1 Hunter Trapping
2 Fast Movement
3 Uncanny Dodge
4 Extra Favored Enemy I
5
6 Special Bonus Feat
7 Trap Finding
(wiki lists swift tracker here but you get that from ranger at this lvl anyway)
9 Extra Favored Enemy II
10 Special Bonus Feat
11
12 Improved Uncanny Dodge
13
14 Extra Favored Enemy III
15
16 Special Bonus Feat
17
18 Scent feat
19
20 Special Bonus Feat
21 - 29 Hunter Trapping gains additional 1d6 MAGIC damage at every odd kit level in addition to the piercing damage it gets now. So a pure ranger-hunter traps would do 30d6 piercing and 5d6 magic to one target at level 30.
Special Bonus Feat List:
Rapid Shot
Many Shot
Ranger twf
Ranger improved twf
Weapon Focus in choice of spear, shortspear, or any ranged weapon
Skill Focus Hide, MS, Disable Device, Set Trap, Spot, Listen, Search, or Survival
Alertness
Stealthy
Any of the hunter trapping added effect feats
Original below
Suggest adding Trap Finding feat to hunter kit level 5 so they can see and recover traps with DC higher than 20. Also, suggest additional effects to higher level improvised traps like fireball, poison gas, etc, because right now I don't think the kit is worth losing spells for except at lower ranger levels. Also, have the Improvised trap stop breaking stealth. Right now a trap is pretty much once per combat against one creature.
ETA: Also, I don't think hunter should get rapid shot and many shot because those are the first 2 out of 4 feats they get anyway with the archery style: meaning that if someone has chosen two weap style they get an added little bit of archery from the kit. But if they had chosen archery style to get all 4 feats of that then what they get from hunter kit is redundant. Instead, what those two feats are should be determined by which ranger combat style you chose; you get rapid shot and many shot if you chose 2 weap style and you get two wepon fighting and improved two weapon fighting if you chose archery style but if you take archery style the kit gives you 2 additional favoured enemies instead of 2 feats you already have. Or possibly skill focus in hide and move silent. Or weapon focus in the ranged weapon of your choice and weapon specialization in the same weapon.
Actually, I think I like that last one best: if you chose melee ranger combat style the kit gives you rapid shot and many shot. If you chose archery style you already have those so the kit offers you your choice of ranged weapon focus and then specialization in the same weapon.
