Per request:
hug effs. Numbers are in percentages: Beetles hug 135% of their own value in Ter Fi (Harpies).
Etd: Yes, they're pretty strong, especially offensively. Pretty wide open defensively too, though, so I figured it'd balance out.
Peacekeeper: I mostly intended them as a viable alternative to using the Ghost's T2 against Ter Bs. Agreed that it's a bit of a bolt-on. Alternative might be to make Peacekeeper T1 De, the Arrowhead T1 Fi, and the Bolt Thrower T1 Bs. My ultimate goal with the Peacekeeper (which this stats probably don't achieve) is to make pre-Siege Xans
wide open to some class. De is probably the best option, here.
