for stalkers generally regen, ninja, or sr for a secondary, for cor i cannot say much
wp is best for stalkers, pain dom is easily the most survivable corr in zones.
Duel me.
I will work on my sig pic more when I have time.
Speaking as someone who PvPs nightly in zone, I will tell ya that your going to find mostly Scrappers as your opponents. I see /Regens & /SRs mostly in RV. Mixed with the Scrappers are a few out-of-place Tankers. Once the zone gets busy, then the Blasters come out - but this AT tends to be really well played or played very poorly.
I post this to give you some idea what is lurking in RV.
Additionally, I've heard that /WP is currently the best secondary in zone for Stalkers.
Thanks for the info! Does anyone have an electric melee/wp build out there? Or can someone point me in the direction of how to IO a Willpower? (def/rech/hp etc?) Have yet to roll a wp and dont know much about the set, thanks! 
general slotting in hpt should get you close enough to the hp cap to not bother with set bonuses for hp
I havent PvP'd in quite awhile and getting bored waiting for GR so im thinking of rolling a pvp toon. Problem is, idk whats good anymore. Personally id like to have a redside pvper so im thinking either a stalker or corr. Ive heard pain and thermal are great sets and for stalkers electric melee seems to be awesome. For stalkers what secondary to pair with electric? And if i went the corr route whats a viable build? (i have a 50 sonic/therm so if anyone has a pvp build for that it would be nce, but im looking forward to making an alt
Thanks!
P.S. I would like this toon mainly for zone pvp, i do see myself venturing to the arena every once in a while though.
