As an member of K'hara faction.
I dont log that much because its <epic sarcasm> totaly fun to see Rogues, Hackes, Xenos, Police, Navy, Order and BHG cooperating just to hunt down ONE nomad across as much as 8 systems(just happened to me once) even into hostile territory. And its even more fun to be shot at with one line engagement notice (note that "one line" doesnt even mean one full sentence) IF there is a notice or RP at all. </epic sarcasm>
As for current nomad tech.
LF was nerfed quite considerably. Currently it is a HF with seriously lacking arnaments.
VHF is quite okay-ish, slightly above average VHF but its very skill dependant.
Bomber is and always was rather mediocre.
GB is rather okay. Its is good versus other GBs and Cruisers however thanks to turrets low refire, it is somewhat worse against fighters and bombers. Also, its not exactly the smalles one around - Big from any angle.
Cruiser have slightly highter speed and recently got its LM equivalent but i cannot comment on that one because i have yet to see one fly in .86 (maybe i will make one).
Marduk is cool, 'nuff said.
AND, note that Nomads dont have ANY cap missiles as far as i know.
As for opening nomads. No... Pretty much all reasons have been said and i take admin side here, as in, i am against.
