Since I have no real experience in CF pvp (just joined recently and I think top ppl online was 6 for now) I still focus on getting rich(ish) and killing as hard npc as I can find.
I just recently replaced my 2xnomad blaster, 2xwildfire mk2, 2x Blue blaze mk2 with 4x DomKavash Annihilator. Main reason was range improvement that I though might help me kill faster and speed improvement which I thought would make them more precise (which is not the case atm).
As for performance, both are energy-hungry, but sufficient to take down any npc wing I encountered in Sirius... problems started to occur when I fought Coalition guys (who don't drop their Gatlings btw). XD
I would like to try out ancient cannon + skyblast b combination... but I'm yet to find them and build another character.
Also, it would be nice to see weapon HUD effectiveness in the weapon stats ((Hu. D.second/ Energy second) because I often divide it manually when I think of setups
