Behold, the power of DoT.

However, from what i've heard, warriors get it worst, then mages, and archers don't even have any negatives, just pure awesomeness.

Mages:
50% stance w/infinity
10% damage increase when monsters are DoT'd, stunned, frozen, paralyzed, etc.
Ignore 20% monster defense
Summons don't turn monsters elementally weak anymore
Advanced Bless
Glacial Chains
Mist Eruption

Warriors:
Power Guard gets buffed
Advanced Final Attack
A bunch of shiny new animations
Dark Impale (exact freaking copy of Phantom Blow, seriously)

Archers:
everything you could ever want, ever.

I see what you mean.
