Does it still count as "Cruiser" Clash?

Actually does, since I do have two cruisers (in the list top left), because it requires an Admiral ship and at least one Line ship. In this case, those are Hellbringers MK2, cheapest ships available (in this case, "Lancefu_ker" and "Lancemurder", Slaaneshi-marked ships). The rest, however, are 13 Iconoclast Class Destroyers, cheapest escorts available.
