KM/Elec scrapper, stalker, or brute? My best advice is just to get out there in a pvp zone and get your *** kicked until you understand how it works better. Once you grasp the system you can begin tweaking your build into what you think works best for you. There are "general" tips and guides that can help you but it ultimatly comes down to your experience!
It's nice to see some new blood in PvP. Melee can be fun but rough at times when the ranged characters gang up on you. Concentrated Strike on a scrapper is where it's at though for some solid damage. Elec armor is not a bad choice as you can get your resist numbers WAY up there.
This will be my first PvP build, could someone run me through or show me, exactly what powers i will need, including pool powers and mastery, for a successful PvP build..
Many Thanks
