As a member of the ministry of luv (please don't hate me), the catalyst swarm (and then vexors for certain targets) is where its at. On a related note, you asked for a napoc fit that works, here you go:

Note this is low skilled shield fit and has a fairly low paper dps. However, it actually has decent damage application for most areas and also is way overtanked (handy for low sp chars and logi).

Bring Navy Multi, Navy Xray and Navy Standard and profit
