If a Sabre flies against a Titan, and the people flying are of the same skill, the Sabre will win. It has more firing time, accelerates to full strafe in 1/3 of the time it takes the Titan to, and has an extra gun. The little energy you have left after an inferno shot can be used with 7 top tier Outcast guns to take around a third of hull from an armoured Titan.
Adrian... do you even know how to pirate? I saw you get killed by a CT in a Templar, which is an even more refined version of the Titan.
And if you want to complain about the Taiidan, then take a little peek at the bomber fleet of the whole SCRA. What are Coalitioners doing with GMG tech? How did that happen? That is where Ivan got it from.
