My fix for this Archtype -
WILD STALKER (ARCHETYPE)
--------------------------------------------
Wild Senses (Ex):
At 1st level, She gains Darkvision 60' and a +1 bonus on Perception checks. This bonus increases by +1 for every four levels after 1st (to a maximum of +5 at 16th level).
"This ability replaces the ranger’s first favored enemy ability and Wild Empathy."
Uncanny Dodge (Ex):
At 3rd level, a wild stalker gains uncanny dodge as the barbarian’s class feature.
"This ability replaces the ranger’s Endurance feat and first favored terrain ability."
Rage of the Wild (Ex):
At 4th level, a wild stalker gains the rage ability as the barbarian class feature, but its barbarian level is considered (ranger level –3).
Use Controlled Rage archetype rules per "Ultimate Combat"
"This ability replaces hunter’s bond."
Wild Talents (Ex):
At 5th level, a wild stalker ranger gains a single rage power, as the barbarian class feature. She gains another rage power each five levels after 5th (maximum of four rage powers at 20th level).
"This ability replaces the ranger’s second, third, fourth, and fifth favored enemy abilities."
Wild Talents (Ex):
At 8th level, a wild stalker gains a single rage power, as the barbarian class feature. She gains another rage power each five levels after 8th (maximum of three rage powers at 18th level).
"This ability replaces the ranger’s second, third, and fourth favored terrain abilities."
Greater Rage of the Wild (Ex):
At 12th level, a wild stalker gains the greater rage ability as the barbarian class feature.
"This ability replaces the ranger’s quarry and camouflage abilities."
Tireless Rage of the Wild (Ex):
At 19th level, a wild stalker gains the tireless rage ability as the barbarian class feature.
"This ability replaces the ranger’s improved quarry abilities."
Master Berserker (Ex):
At 20th level, a wild stalker rage ability and rage powers equals his ranger level.
"This ability replaces the ranger’s master hunter abilities."
My suggestions:
Wild Senses - Strong Senses was fine. I would revert back to that ability, having it only replace the wild stalker's first favored enemy, like normal.
Uncanny Dodge - I like how its not replacing Combat Style anymore, but it should just replace either Endurance or 1st Favored Terrain, not both (my vote would be Endurance). The let them keep their 1st favored terrain, and have that favored terrain progress as normal, but not allow the wild stalker to choose additional terrains. In fact, you could just him Terrain Bond, from the Warden or Guide archetypes, at 3rd level, and not have it increase any further.
Rage of the Wilds - Dig this change.
Wild Talents - I would revert back to the original wild talents ability, but just have it start at level 5, and then again every three levels thereafter, replacing favored enemies 2, 3, 4, and 5 and favored terrain 2, 3, and 4. This would mean that you only needed one Wild Talents ability (btw, its bad design practice to have two abilities of the same name). Wild talents would then be gained a total of 6 times by 20th level. That is 6 rage powers or 6 skill increases (which should have a cap of +8 or something.)
Greater Rage of the Wild - Dig it, but just have it replace Quarry. If you let them gain their first favored terrain, then camouflage would still benefit them. Besides, you don't replace Hide in Plain Sight with anything later, so this would be more beneficial.
Tireless Rage of the Wilds - Dig it.
Master Berserker - First of all, this ability isn't very clear. Not sure what its benefits are. Instead, I would just change the name to "Mighty Rage of the Wilds" and have it function just like the barbarian's mighty rage.
Alright, but I still would rather have mighty rage, which gives a +8 stat bonus to one stat with Controlled Rage, or four increments of +2 to be put into STR, DEX, or CON, than the extra 6 rounds of rage that the current Master Berserker ability is granting. At 20th level, 6 rounds of rage is minuscule, and hardly worthy of a capstone.
