Highest possible damage class

Hi all,

I am interested in what you think is the highest possible damage output a class can do?

I am thinking splinter barrage ranger, spirit rit, EA Fire Nuker?

What is the highest possible damage output class with buffs and support from other party members?

First, are you talking about burst damage? AoE or single target spike? Sustained damage?
Flash Dilithium dealt decent amount of damage with his turrent ranger build.

I am talking DPS be it AoE or singletarget as long as its not like a single spike every 10 seconds or so, must be sustainable.
