if you want knight to do damage, just give them a perma swordcross, that would balance the fact they can only wield 1 item (2handed weapons) and they d do some damage
if you want satan unchanged, give melee a long range skill (oh yea guillotine/aoe/special hit/charge are such a long range

),
I don t see why you d want a crucio back to 200% when you can actualy satan the target and move away, crucio isn t ranged as far as i know and if a ranged class attacks you, well psys are ranged too. So not back to 200%, maybe 100% but not over
PR should be back to 50% I agree with that (if it were to be 50%, i wouldn t want a perma swordcross though, but still stronger skills or/and a 50% change of swordcross because needing nearly 8-9k atk to only deal 3.8-4ks keens without an pvp damaging ulti is just well unrealistic)
fixing special hit of course
sneaker should be like a windfield effect (just not as long as it)
about asal being a 1-hit-ko skill, yea maybe, I was just thinking of how asura from ragnarok online is, it s that same type of skill, it just can t be used so often making pvp different from how flyff is with asal.
I disagree with the category you give to classes though, being a god in pvp should rely only on the player skills, not on the class itself
