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.

 Spoiler

My range is 26,707 to 38,153 in this picture (my clean range). Dividing the ME damage by my max range yields 274.58% for the highest hit. After a few minutes of testing the highest I saw was 115k which is close to 300% damage.

I'm not sure if that means critical is actually working and not showing in color, but the damage is DEFINITELY doing higher damage on certain hits.

Edit: Wow, got completely Ninja'd by the posts before me. In short, ME can critical...
