The All Range Fighter, Knuckles/Magic Device

Swords have berserk rampage
Halberd has war cry and chronos
Katana has shukuchi and so does DW
Mage and MD has maximizer
Bow and BG has decoy shot.
Knux has a +5 ampr passive and a long cast ampr buff which gets removed when hit also a chancey prorative def break which gets dicked over by a knux passive.

Only knux is unreliable in mp recovery.

Following, knux is the best in hp recovery with the amount of skills dedicated to that and the relevant combo tags.

For knux/MD, knux can abuse their high recovery rate to take advantage of resonance for mp recovery and actually do away with mp charge so there's only need for low cost combos

 

Sorry but this is hilarious. All the drawbacks you've mentioned are exactly the issues we're facing but you've decided to separate "LOW AMPR", "BUGGED SKILL" and weak "GODHAND" from Knuckles' low damage. Big brain, right? Also, Crusher tiers are released later and so their tier 1 skills are equivalent to tier 2. Otherwise they might as well not be used


Edit: Also, anyone who has touched Knuckle dps would notice its low ampr. Terribly slow auto attacks even though it's an aspd class
