How can I tell if I am doing enough damage?

[Awful]

All I can say is:

-Practice, Practice, Practice I can't say this enough about DPS or people who seriously want to improve i'm constantly trying to find ways to squeeze in more DPS as a smn in every encounter I do.
-Look up guides, rotations/priorities (and learn the difference)
-Do stone sea and sky
-Learn fights inside and out if you're a blm or melee know when to go ahead and use positionals or don't move at all, if you're a smn learn to manage your stacks effectively
-Know what you can get away with, if you have a solid healer who'll let you take risks in raid content let em know and synergize
