Oh, i actually messed up thier guns. They only have 2 PD, not 1 Flak. Yeah, that one is even worse against small ships then the Flak.Yes, the FE 'Gamma' escorts seem to be basically small cruisers with 1L + 4S + 2PD weapons.
They only have 1 large more then a normal destroyer. Wich is wasted against small ships. With the bonuses they might come up to the firepower of maybe 2 corvettes in small guns.
Aside from the Spiritualist and Fighters, Escorts are the only FE ships with decent weapons against small targets.
The Xenophobe does trade all thier medium slots for Flak 2. Does make them realy tought PD nuts to crack. But it makes their ability to kill Corvettes and Destroyers even worse then normal FE. That they actually go towards your ships does not help them either.
