I agree that there is a huge difference between fighter effectiveness
from 213 to 213c, however I don't think that it has to do with being
vulnerable to ship speeds. Doing a sim with the aforementioned t-rex
and 900 type 2 peep fighters with 213 the fighters won with only a
loss of 100 fighters. With 213c the fighters barely get through any
armor (a feature of the T-rex no doubt, eh?) before being wiped out
and 2 wings die off just when getting to damage the hull and 3 wings
kill it and get a way with 400-600 fighters remaining.
First off I thought fighters were way too powerful in 213 to begin
with.
I didn't really notice that the T-rex gained that much of an advantage
from maneuverability, it has more to do with the fighter's adjusted
firing rate I'm guessing. It appears to me to have gone from 'Near
instant death' if a ship were to stumble within range of the fighters
to 'Advantage ship.'
Perhaps somewhere in the middle??? Dunno...
