What Parse and how to Set it up? (Question)

[Rainsford]

So if you're a job class who uses DoTs, your full damage is not going to show up on the parser. Someone please correct me if I am mistaken.

As someone else posted, it runs a simulation. So if you cast a 30 potency DOT that lasts for 25 seconds, it will approximate the damage over that time period. Super accurate? No. But if you're talking about an endgame fight where you're doing 80k damage, 2k in one direction or another because of dot crits/etc won't have such a huge effect.
