here is an example of items you can use and get easily to have a good pvp setup:
(this is not a complete setup, just a few items i see alot of people without)

+hp braclets
+hp perks
these are items most people can get with a little help or on their own, and it makes a big diffrence when your pvping, hope it helps!
And feel free to try anything you think may work, this is just my suggestion. You can get the kegern armor at Biodome raids, the implants you can blitz on your own and the NCU items are easy to find
edit: i made some of the implants ql 200 on accident, they should be ql 250
