How hard is 1700 arena rating?

First time to sit down as RSham and grind in a couple hours to 700 using just SoloQ 3v3. I got the healing lvl 251 totem. Still consider myself a beginner and my addons keep clunking out too. All Ive been doing is heal like crazy, interrupt when I can, drop totems, pop BL/Hero.

As a PVP player I enjoy BGs more and have little interest in arena but for the Rsham I want to get the 270 healing totem for PVE too.

So Im wondering how hard is it to just get to 1700 and get the totem? I play on Icecrown, 6060gs with 1300 resil
