I must admit it has been mainly smaller games I have had, mainly cruiser clash where I took an upgraded Tyrant, gothic and lunar and seemed to do fairly well, I mainly had the lunar Support the other two, either stripping the shields of enemy cruisers so the Gothic could fully use it's lances, or supporting fire onto a cruiser the Tyrant had already stripped the shields away.
In this list it is mainly to bring an extra nova cannon and lances, as I admit after my first time actually using one I had good luck with and so I want to try and get a few more into my usual lists.
The main problem I can see for a second lunar is the first would not be able to work with it due to staying back to use it's nova cannon.
