This is the way I see how the monk works:
Spirit generating abilities are your damage dealing skills, whereas spirit spending abilities are your utilities. This is because the majority of spirit spenders are utility spells, and there is not a single spirit generating ability that doesn't do damage. Now I understand that there is a few spirit spenders which do damage, but I feel like no monk build should have more than 1 spirit spending damaging ability, and that ability should be used only in circumstances where you have excess spirit.
With this is mind I built my monk without
items that have +regen spirit (e.g. inna's weapon), and strictly went for balancing damage and survivability stats. Seeing that I play nothing but hardcore (solo mostly), I'll need some survivability and I figure a dodge monk will do fairly well in hardcore. This leaves a fairly straightforward build for me. http://us.battle.net/d3/en/calculator/monk#cUdbXY!ZVW!YYcZYa
While it isn't the best dodge monk build, best damage dealing build, or supportive build, I feel it has versatility which is crucial in hardcore. It also needs little spirit to do damage and thus there is really no reason to have +regen spirit items like inna's weapon.
Now this is all theory-crafting and what not, I have no idea how well this build will work without actually playing the game, but thats my thought process in building my monk.
