4th job Single Target DPS

1. Apples don't have the crushing impact on the order of which classes do the most damage that everyone thinks they do. In fact, they don't hardly change anything but push NLs with SE up a little more over Bowmasters. The real advantage NLs have with Apples comes from Alchemist. Fewer Apples used = less cost to the run.
2. Download the Excel spreadsheet. You'll get a much better understanding of the data. Apples are on there. Just put 100 for "Att from Potion". The data listed is just for fun, not really to inform anyone about anything.
3. Yes, Buccaneers are not a great DPS class at bosses. They are like NLs in that they do average damage solo, but receive an enormous boost in damage with SE. However, as Stun Mastery doesn't do anything against an enemy that can't be stunned, their "enormous boost" doesn't exist against bosses.

The damage for Buccaneer, is it including critical or without critical?

And which class is stronger? Shadowers or Bucc on bosses?
