3.55 PVP Balancing.

[Llus]

In a vacuum, MCH's burst can be easily countered too, just like anything else. The goal is to create and exploit situations where it can't be.

I don't think warrior is overpowered exactly, but it probably is too out of line with the other jobs filling the tank role in its burst damage dealing capability. Could stand to have damage toned down a bit in exchange for more utility.

DRK and NIN need buffs more than anything needs nerfing

WARs don't need a nerf. We trade high damage for very low utility. Brutal swing every 20s with only a 3s stun with HUGE DR is almost pointless in feast. Mythril tempest, even with a 3s stun and knock-back tends to be an emergency-only tool (again another HUGE DR stun). The only real useful CC skills a war has is storm's path for damage reduction and holmgang every 180s (and if burned late in the game can easily lead to a loss if you're hit by mele LB and don't have it up)

WAR burst is easily managed too:
You see berserk? WHM: fluid-aura, sleep, PLD: stun lock, AST: stella, blizzard 2, sprint, BLM: sleep, MNK: axe kick, DRK: carnal chill &/or unleash,
Did you get holmganged? Do you have purify? Purify, sprint laugh. No purify? Attune. No attune, that's where your own team needs to help you; too bad you can't ask for that help in feast though.

I'd rather see PLD's stun get nerfed, but PLD stun lock, silence and pacification really what makes that role shine in PvP. They're the king of CC and party support where WARs make up for lackluster DPS while leaving their healers out to dry. DRK definitely needs some help; but they've already gotten a HUGE boost to their CC toolkit that they sit right between PLD and WAR for CC & burst damage. Their burst damage, while easily hitting 850 potency in a 4s window; lacks the bonus that WAR's 1000 potency burst gets from maim, storm's eye and berserk. I think the toolkit is there, but exceptional DRKs are going to be hard to find and I think it will take an exceptional player to make DRK shine - PLD and WAR are both easy to play in feast, while DRK's AoE bind and heavy are easy mode for FL.

As a dark reaching top 100 two things I think would be benefical. Make represial a 30 second cool down in the feast, not requiring a parry. This would add slightly more utility and make you question if to attack focus target or to play supportive by reducing a targets damage by 10%. Secondly reduce the cooldown of carve and spit to 30-45sec from 1 minute, other than that I don't think were too bad.

I think these two would really improve DRK for both feast and frontlines. Still, playing DRK to a high level is going to be MUCH harder than PLD or WAR since they sit right between the bursty mode tank and party protection mode tank. Like you said, the toolkit is just about there and with a few tweaks I could see DRKs played at a very high level make top 100 much more often.
