You're too worried about what better players are using to clear content. Each skill you have should be used in its own way. Skills are there to compliment your gearing deficiencies.
I have low HP, so I use an Ally to tank and distract for me. I have very high dps, so I use sweeping wind so my damage can keep going while I kit some.
Low survivability, so I use dodge mantra with hard target, with resolve and concussion.
Build around yourself; not others.
Also, it's really irking me to see you guys constantly asking what runes people are using. 4/5 times, you should KNOW what they're using, just by watching. Hmm, lightining coming out of auto attacks... Three healing mantra buffs on bar...
tl;dr: The main problem with the class is that nobody understands how to play it. Learn the game a bit, instead of always relying on others to beat !@#$ for you.
