Preface: I love this game. Completely satisfied with purchase.
I think a lot of the perks in this game are useless. They need to be scrutinized a little more and they definitely don’t jibe with a hardcore play through. I think the general philosophy of perks in all games, but specifically this one, should focus on rewarding skilled players, not making the game easier as you get better (Some of the perks in this game accomplish this). Obviously you are not forced to pick perks, but a lot of them are just carrots on sticks and could be replaced by systems that actually improve the game for skilled players.
For example:
Revenant: passive health regen…why?
Light Armor: not wearing plate armor=50% easier to dodge strikes…just make armor scale correctly and let my skill decide
Thickblooded: bleed slower…unnecessary
Firm Grip: shield blocks cost opponent 15% more stamina…your kb+m shield skill progression should be sufficient
Berserk and Blood Rush are pretty egregious
Everything in the Warfare tree (excluding Bailman & Feint)…just no, all filler nerf material
There are others…
Most of the perks in the Skill (alchemy, reading, etc) trees are good, make the game more enjoyable
The ability (dodger, perfect block, etc) perks & the combos are good.
I like the tradeoff perks: gain 20% here but lose 10% here and here.
Ideas for useful perks that reward skilled players and make the game more enjoyable:
Need an archery tree:
Pin in Place: temporarily immobilize enemy with foot shot + non-plate boots, other precision/skill shot perks.
Arrow Crafting: fire arrows (near campfire, etc) , other realistic stuff
Maces and axes:
Stole My Ballons: strike to plate helmet has chance to lodge weapon, basically zombifying that opponent, but lose weapon.
Mine, Mine: Lodge weapon into wooden shield and disarm shield.
Catch This: Throw weapon at head = immediate KO, possible death depending on headwear.
These may require an easily retrievable secondary melee weapon.
Those are just a few, I’m sure you guys can come up with more, better.
