Ronin/Samurai abilities

[Zanmato]

You call it a melee and ranged hybrid with high attack power and low vitality, but it has high evasion and high parry and the ability to heal itself, largely countering its drawback.

It has very strong debilitating effects.

It can restore 100 TP and 18% MP to the party every 2.5 minutes. Compare to Shroud of Saints, which currently restores about 1000 MP, a bit less than 25% (and it's not a %), to the WHM's MP (and nobody else's) every 2 minutes. Also steps on BRD's toes.

It has some powerful abilities with 15 minute and 1 hour recast times. The game is balanced around 5 minute recasts.

It can give Dragoons the ability to play well. That alone breaks the game.

Hahaha! That DRG joke. ^-^ Well... I guess I can adjust a thing or two.

Just want to point out that in order to get those 18% (now 8%) MP is decently expensive (300 TP).
The self-heal costs 2 stacks of sorrow, which is something you don't have every day and should be careful with once your timer starts to tick.
The heal from canceling the Burn is something that you may not want to do, based upon how many stacks there is, and concerning how much damage you lose from canceling it.
The innate healing resistance also reduces the percentage unless mentioned otherwise. :3

The reason for the long timers is due to just that, the moves are so good that they should require a long cooldown.
The parry is merely effective in Earth Stance, and the job itself is demanding to be played in Fire stance, or you will lose 20% damage/slash.
However, you are forced to revisit Earth Stance for the movement speed buff to get to places faster and keeping your dps going.
