dude no AV is already a threat as is, Spec into a better swarm launcher. theres plenty that kill much better, from this post it sounds as if your using the starter.

You can make your swarms something to be feared, even the basic swarms, it all depends on the type of mods and what you have skill wise. Remember that each missile has to have full contact to get the full damage and with all the ways that you can increase the final damage output.

You can make swarms deal up too and this using the Prototype swarms mind you, with 2 complex damage mods so your light weapon damage is 1.21%, weaponry 5 and Swarm Launcher Pro. at 5 that the over all damage, that will be 2070.1 damage and say you was facing a tank with2 15% armor resistors which adds up to 27.5% resistances and about 8357worth of armor and no more than 1500 shield, the first shot/volley would take off the tanks armor to a total of 5717.6 that is not adding in the shield though so keep in mind and I'm to lazy to add that into the match part. Regardless take a little time out of the day to do a little math in game with some gear if you want the best out come for your weapons.
