Ideally with this build, you'll be using crippling wave (concussion) and dashing strike (blinding speed) to leap around the area debuffing mobs while tanking very little damage and getting as many mobs to chase after you as possible. Recasting Mantra of evasion (Backlash) and Breath of heaven (blazing wrath) are your emergency buttons and seven sided strike is your finisher and/or a massive emergency button.
A few things I'm not sure of with the build are the use of breath of heaven (blazing wrath) with this build instead of Serenity and what to use for the 3rd passive.
Since I'm planning on running pretty much with a premade 4 man group consisting of DH, WD, and another, breath of heaven would probably be better overall utility since it would allow me to spot heal allies getting beat up while I take aggro back even though serenity is a better overall emergency button
One with everything will probably be the best 3rd passive for this build with poor gearing. If you can get roughly 50%+ crit chance, sixth sense will probably be the best (as well as switching sweeping wind's rune to cyclone). Transcendance could also be pretty spectacular seeing as you would be spamming dashing strike for a 1550 heal frequently and it turns recasting mantra of evasion into 3.1k heal and additional 15% dodge chance which is especially great seeing as this is a moderate to low spirit usage build. This also might warrant the use Mantra of healing in this scenario depending on how little damage you take due to your mobility. Near death experience is probably the generic safe choice.
Overall, with the base build you should be rocking 50% dodge and 45% enemy damage reduction consistantly (for a total mitigation of 72.5% not including resistances, armor, and slowed attack speed) and peaking at 65% dodge and 45% enemy damage reduction (80.75% total mitigation). If you can hit 50% crit, you can increase this to 89% total mitigation with sixth sense
My mitigation numbers were created by taking % chance to not dodge multiplied by 45% then added to the total chance to dodge. This entails how much damage you would take in comparison to another class/spec as opposed to how hard mobs will hit you.
I will be the first to admit that I'm not the most familiar with new mechanics of this game, especially in regards to my potential spirit generation so if you have any suggestions, let me know.
