I might try the madness that is PvP, especially as somebody who normally has like a 0.5 k/d on games like CoD.
Any tips/suggestions or should I avoid all together?
Don't avoid it my friend. I loved the PVP in the beta and the iron banner events are insane. It can be a lot of fun.
Quick tip: If you're struggling to get kills then just try to concentrate on capturing zones. If you can get 3 you get a "hat-trick" achievement and a fair few points. Just don't get caught up too much on your K/D. I played a fair few matches and only just managed a 1.00 ratio.
Also as a beginner make sure to stick with your team and just support them during fights. Don't try to solo the MP or you'll get destroyed.
Nice load-out to start is a Cydonia AR3 auto rifle and a fusion rifle as your secondary. The fusion rifle takes a bit of getting used to but does lots of damage.
Good luck dude.
