because I'm lazy and don't have to change hardeners. rats don't hit all that hard, and dead rats hit even less hard. and that way I don't have to worry about having a resist hole. although with em/therm hardeners kin and exp are the lowest shield resists, but exp and kin are the lowest armor resists.

Laser ships work best with caldari drones.

It's nonsense, caldari drones are failbad unless you need super long range sniper sentrys.

Caldari drones are so bad that even vs the kin weak factions gal drones are better, for angels (not that you want to be doing angel missions in a nightmare) use min drones obviously.

It is true that you want to use as much T2 as possible to avoid being a gank magnet, my setup is a lot cheaper than it was, back when it was a 3 bil fit I survived a 6 bs gank, they shot me on EM which with overheat was at like 85%, I lol'd hard but quickly reduced the number of faction mods on my nm to 5.

LOL caldari drones and NOS are definitely not needed. You should only use hobgobs and even then stuff will die before your drones can even get to it most of the time. And if something gets withing NOS range you shouldn't be flying a NM in the first place as you can insta-pop frigs, cruisers and most BC at range then just 4 volleys for BS.
