Ninja seems a bit broken

[LunarEmerald]

Ninjas have very high dps. On par with monks and have faster start up and don't have to worry about losing GL stacks
Kassatsu lets Ninja have high burst. Raiton -> Kassatsu -> Raiton (guaranteed crit)
Their ninjutsu is free to cast. They even have a fairly strong range attack ninjutsu they can use for free.
Their increased speed makes it easier to avoid aoes and attacks. And unlike monk, they don't sacrifice their dps to have that speed.
None of their attacks have positional requirements.
They have an easy to access silence and stun.
Goad is on par with peaon for a single target and it doesn't decrease their dps.
Their perfect dodge lets them avoid any physical attack in the game. This includes dive bombs (T5), meteor stream (T9) etc

Ninjas are OP
