4th job Single Target DPS

That's not how critical works. If ME with Greed can critical, it would do up to 360% damage. Your criticals will do at least 1.2x to up to 1.5x damage. I tried dozens of times in Tespia and could not get anywhere near to where even a minimum critical would put my Meso Explosion. Post the screen shots here or send them to my PM please.

Augh. God. Looking at my posts about Tespia, it appears I had concluded that Greed gives 1.6x damage, not +60% damage. If it does do criticals, it is obscenely difficult to catch because of the seemingly unrandom distribution of damage.
