4th job Single Target DPS

This table is a comparison for uber equipped characters at level 200 against a snail. Being low-leveled is not an excuse.
You could, with similar reason, argue to include fire arrow DPS for F/P mages since it isn't until later in 4th job that they'll have paralyze maxed. Or even go further and don't include maxed BE, SE or hurricane for bowmasters since that takes a long time to max as well.

Then why include a calculation for Marksmen not using Snipe?

Blaze doesn't have the *greatest* of range, Killing Wings does. Some people could use Killing Wings over Blaze for that reason, and if your going to Include Phantom Imprint and Illusion Spam in the dps calculations, there is no reason for Killing Wing not to be used either.

Also a question, would using Final Blow for Arans in 1v1 hinder their dps in the end?
