I have heard that pvp gets really hard in later levels. My pvp rank is Adept/Deadly, should i use all my energy cubes and tri matrix emblems now to get a better rank now or what do you think? I was wondering what a pvp ship build is? And here are the things i have got on my ship
Weapons Phase Cannon x3, Dominion Cannon ( 2 red badges away from another!)
Energy Omicron Injector
Sensors Stryll Transponder
Hull Ablative Whipple Plating x5
Shields Harmonic Resonator
Cloaking Zolazin Jammer
Defenses none
Any tips on what to reserch or anything should i stick to weapons im on phase cannons 2/3 and i have just finnished ALL the whipple platting reserch? What should i go with and for how long should i stick to that reserch tree?

If you're planning for PvP, focus on weapons, hull and defense. Always research the whole set of something straight through, because: (A) the last step module in a tier gives the best value per deck and (B) it helps you keep track of what you have researched. I recommend always upgrading your modules from last step to last step (ie.. Heavy xxxx Cannon to Heavy yyyy Cannon) but at lower levels things are relatively cheap and you should be able to upgrade to the intermediate modules. Hull repairs are cheap for you so don't bother putting shields on your ship (hull is a better point to deck ratio) but you'll want to research shields from time to time just for the planet defense shields.

Hoard those energy refill artifacts like a squirrel with acorns. They become much more useful to you later in the game (unless you need some energy to fight an elite or something that drops really good stuff like a TO Troop Carrier).

i dont know what others think, but i rekon saving up your red badges and going straight for the dominion Mk III is the best idea... those MK I's are tempting and rank 100 seems like a distant star but its all achievable.
