Rogue/Rogue 2v2 ArenaFollow

A friend and I were going to try out our rogues in 2v2 arena. We just want to try it out for a fun factor for now as we get most of our points from our 5v5 team that is doing quite well. He has S2 Maces and I have S2 swords and we both have all pvp gear with about 10.5k health and 350ish resilience. We tried out both being Shadowstep but after the initial burst it seemed we were screwed if a couple heals got off or some ability dodges and misses didnt go our way. He has since respecc'd to AR/PREP to try to compliment my Shadowstep build. It seems they may work better together than two ShS builds. Would you agree with this or would it better for me to spec AR/PREP as well? Any advice on would be greatly appreciated along with any tips for some of the harder teams we will face. Thanks!

You'll lose to CC and any anti-CC class, i.e.- Paladin.
