Some observations:

Ran a pair of OTAs and a pair of NCOs in ~50 minutes. I'm finding that raw DPS is less of an issue, and switching targets + slowing things down with sufficient webs to blap the frigates to be more of an issue. Unfortunately, my Loki pilot has terrible paint skills, perhaps paints would help a bit, or fitting four webs. It seems to take 2 cycles of 2 webs to sufficiently slow down a frigate so that gardes w/ 3x omnis w/ tracking scripts can blap them. Then I spend 1-5s waiting on the webs to cycle before I can get going on the next frigate.

Briefly tried ogres, that was terrible with drone travel taking longer than the 2x web cycles.

In the OTAs, I was typically able to lock/blap the niarjahs before they jammed a ship. Sometimes they would jam the logi, mostly it was a random rattlesnake. Otherwise all the ships closed so fast that I never needed to switch from tracking to range scripts.

Going to try again tomorrow, dropping the adaptive on the Loki for a 4th web. Going to be pretty low on tank, but the Loki did only get hit once and it was orbiting the beacon and tanking very easily.

So far, Vanguards seem to be loads easier to setup/secure than c5 sites/escalations. The ISK is maybe 2/3 of what I'd typically earn, but it's safe and requires minimal prep work and no salvage/loot collection.

Final conclusion is that Vanguards are broken ISK faucets, and I'm going to run them until CCP makes it not possible.

Going to see how the four web shield Loki works. If that works well, I'll wait until I've got Ishtars trained up and give those a whirl + consider going armor. Would give the Loki more buffer, I could use 2x Nestor instead of 3x Basi, I could go triple omni armor Ishtars, and the DPS output would actually go with by gaining another DPS pilot + Nestors.
