I am a newbie myself but I try to use only about half my jin up for the fight so I have a little base for the next one. Specially if I am the puller and go crazy

I tend to pull with Storm stride which means I do need some jin to start with to make the pull. Then I always use crescent kick to do the actual pull which gives me 2 Jin to work with. Then I go ahead with boundless fist and 6 Dragon strike (like you to get the weakness addition). That already gives me around 8 Jin because even if I miss some I normally have at least one or two criticals with additional jin gains. Now my end is normally low and I am now able to use Ashen Hand at least once or twice in a row, which gives me at least one crit most of the time and my endurance is enough back up during that time to start over and get my  (during that time) around 4 Jin up again. If something gets hairy I can always blow out all my Jin with Ashen Hand.

I normally also throw in some deaggros and/or blocking moves.

I don^t have much macros yet. One for pulling only right now. I find the use of your abilities extremaly situational.
I do have my different weapons on my hotkeybar to switch them fast if needed.
