Lokis are overkill.
At some point in the 2nd pocket of "The Assault" mission I noticed that most of the battleships were bunched up and decided to take a snapshot. There are also 2 more Dominixes at range that did not make it into the picture (although their railgun fire did). That's 3 Battlecruisers and 8 battleships in that picture. Current state of my shields?: 100%...
I chewed through a lot of ammo in that mission.
