I have three fleets, all quite large.
Chaos fleet with 1 battleship, 10 or so cruisers, 2 grand cruisers and a bunch of escorts
Ork fleet with 2 battleships, 6 cruisers and either 6 or 8 of each type of escort
Imperial fleet with 1 battleship, 10 or so cruisers, 2 strike cruisers, lots of imperial and marine escorts and an admech light cruiser.
Id be willing to play assuming I could go to the bash.
