Biggest problem with a VSD isn't the speed or armaments. It's that it can't use an ECM, and is left hanging there with no defense tokens.
Also called being apart of 92% of the Imperial fleet.
Not to sidebar this discussion but interesting trends have emerged after 4 waves here. Defensive retrofit is practically a rebel only slot, so is the evade and thus TRC. Support teams were almost rebel exclusive, the Interdictor changed that considerably. The Imperials of course have a much higher black die count, more plentiful weapons team slots, and now the exclusivity of the experimental retrofit slot. This isn't a complaint, just an observation.
Getting back to the accuracy, brace issue... Imperials have and will continue to accept that weakness. Even though I love my upgunned 155 ish pt ISD2, I'm interested to see how 2 VSDs will do in it's place.
