Monks are a pretty well rounded dps class so if they had burst they would be
too strong.

Monks mobility is very good
Fists of Wind Move speed increase
Shoulder tackle (30s cooldown vs 90s on Spineshatter dive / 180s Dragonfire Dive

They have nice utility
Arm of the destroyer (Silence) / One Ilm Punch (Buff Removal)
Mantra (Increase healing +20%)

Position Requirements are lenient
Position requirements for monk enhance potency but you aren't shut down for neglecting
them in battle. You receive the 10% damage buff from twin snakes when used out
of position. Dragoons don't receive their heavy thrust / impulse drive bonuses when
out of position
