Fighter pilots got STR-1, BOD -1, DEX +2, RFL +2 with the Glass Jaw and G-Tolerance traits.
The Naval Pilot phenotype get INT +1, DEX +2, RFL+1, STR-1, BOD-1 with the Glass Jaw and G-Tolerance traits.
The difference between the two is one point of Intelligence and one point of Reflexes, plus or minus a Life Path.
MechWarriors, Elementals, and ASF types, on the other hand, differ enough from the human norm to worthwhile.
This is for one phenotype, for one of the sixteen or seventeen Clans, of one of the thirty or so factions a character can come from. For the sake of brevity, folding them in with the standard ASF phenotype does not really strike me as that big a deal.
With regards to WarShips in general, they are rather like introducing chainsaws to a game of Scissors-Paper-Rock with the rule that chainsaws beat everything and you can use it to cut off your opponent's hands.
If there are too many WarShips around, every other combat branch- and BT is really about 'Mechs- become useless. It is recognition of that fact, rather than WOMG WE HATE TEH WRASHIPZ! driving their marginalisation. And, if nothing else, they go out swinging.
Kinda sucks to be the Ravens, but they are not one of the premier Clans, let alone factions. When AToW gets more supplements, they might get something then.
