What the least powerful fleet required to make any progress whatsoever in this Raid?
If I'm not mistaken, it must be a Siege Fleet.
I have a fully outfitted Cannoneer fleet, a few outfitted Punishers that are not currently engaged in a Base Parts Expedition, and a fully outfitted Punisher fleet that is; and a couple of Buccaneers built but barely outfitted with anything beside Thuds. I had a fleet of Hammerheads, but I scrapped them because I thought they were useless.
I tried playing a raid a few months ago, and gave up shortly after it became immediately apparent I didn't have the fleets necessary to compete at the lowest level.
I just tried a new fleet I fully built out: Cannoneers, in a 63. I figured since this was a recently awarded fleet maybe I didn't have to start at the lowest level. My fleet was destroyed within a few seconds after it approached the first defensive position of the base.
How are Cannoneers properly built? I put the Millenium cannons on them which seem to have been made for them. Should I have put Particle of Phased Attack cannons on them?
