Most pilot abities state "another Friendly ship" which obviously means it's ability works for friendly ships and not itslef.

"Epsilon Leader" states "each friendly ship at range 1" since according to the faq a ship is at range 1 of itself and friendly simply means of the same faction; does epsilon leaders ability apply to itself as well?

Yes.

Unless it says another or something like range 2+ anything that affects friendly ships, effects that ship as well.

I know it may not be true of all people, but the general rule is that you are friendly to yourself.

in the FAQ somewhere it states that you are to be considered within range 1 of yourself.

(Rules Reference page 12 - Friendly)

All ships controlled by the same player are friendly ships.

A ship is friendly to itself and can affect itself with any of its abilities that affect friendly ships unless those abilities explicitly affect “other” friendly ships.

thank you all for your input. I thought it worked that way just needed confirmation.
