Missiles have their drawbacks, but mainly at longer ranges as the target you are shooting at could be gone before your damage is applied. But for short ranges it works very well, flighttime is negligible anyway.
The anti-support cruiser is a good one to have along to deal with frigs and ceptors.
You could perhaps use something like this:
[Caracal, anti-support caracal]
Ballistic Control System I
Ballistic Control System I
Large Shield Extender I
Invulnerability Field I
Target Painter I
Large Shield Extender I
10MN MicroWarpdrive I
Assault Missile Launcher I, Bloodclaw Light Missile
Assault Missile Launcher I, Bloodclaw Light Missile
Assault Missile Launcher I, Bloodclaw Light Missile
Assault Missile Launcher I, Bloodclaw Light Missile
Assault Missile Launcher I, Bloodclaw Light Missile
Target painter helps the rest of the fleet and ship has a decent buffer (15k ehp against uniform damage).
Locktime can be important but given this is a support ship and in the 8-10 sec it will take to lock nothing should be dead, at least not from the ships it is meant to counter. Especially if the fleet it is helping is a BS fleet.
(this is fitted with Linneas skills though)
