5 point Battle:
Points 1 & 2
the kind of big games Crusade era loves. I'd start with the Warlock-class destroyer as a solid flagship; That gives you one big ship of the line capable of taking on pretty much anything in the game with a fair chance of victory, along with a command bonus.
Point 3
You will need some initiative sinks for the Warlock to get the main gun centrelined. 2 assault variant Hyperions are pleasantly tough for skirmish ships and also do double duty as decent troop transports in planetary assault missions. Add in an Explorer-class and you have a beam-tanking scout able to redirect missile salvoes, as well as some extra 'furies.
Point 4
With the scout to tag missile salvoes for you, additional missile racks are a nice idea! The 4 Hermes give you a decent spread of missiles, with space for another 4 patrol choices - Either more Hermes, Some Myrmidons, or some of the excellent Firebolt Torpedo bombers could be used to fill out the numbers.
Point 5
That's a lot of initiative sinks, so a second Heavy laser won't overbalance things too much. An Omega-class destroyer would offer the Warlock some nice heavy backup, as well as a stern laser in case someone gets past you.
That gives you a nice fleet with only a coupl of blisters of fighters or patrol ships.
