Why choose the ships they did? Quite simple, Blackwidow. Let's see you fly even a destroyer in Tau-23. Hell, capital ships are mostly deregulated, let's see you try dragging a battleship through that rock field.
It's a case of people adapting to the environment. The Outcasts wouldn't waste a battleship or destroyer there when it wouldn't even function well, they'd use smaller ships like bombers, gunships, and Scimitars - while they could use a few improvements, even a pilot as crappy as I am can chase off Titans in it.
You're whining about people using maneuverability? So, what, you only fly capital ships because they turn like bricks? Or are you just ticked because you're terrible at dealing with light fighters? If it's the latter, I've got a Loki I'd like to chase you around with.
Blackwidow, I'm being nice here when I say your post was completely devoid of anything resembling intelligent thought, and I'm not even a member of CCS.
