I highly recommend to watch Mirais last videos about the pro system, if you wanna max out your dps/healing in pve and are using IS Boxer.

I have a shaman too and she is doing fine with her gear.

Another site, which i use to compare my dps and for building my macros/prio system, is http://www.noxxic.com/
Just choose your itemlvl and compare
