Playstyle & Rotation
In general as a healer your rotation will be dependent on the boss fight, damage intake and who is in your group, so I’ll just provide some general tips.
A good tip is to make sure you have Ancient Teachings buff up as much as you can by rotating your Faeline Stomp when your Essence Font / Thunder Focus Tea combo isn’t ready. Speaking of which, make sure that if you are playing Upwelling to try and pair your Essence Font up with your Thunder Focus Tea spell. There will be some situations where you won’t want to do this, but it’ll be very very rare.
Try to keep one stack of Renewing Mist on cooldown at all times and if needed, save the extra Renewing Mist charge for when you have a high AoE burst that is incoming. If you are playing Focused Thunder, you want to use the rotation of TFT > ReM x2 > ReM once > Hold ReM charges till TFT off CD > repeat, something like this should work.
MW playstyle is very much centered around spreading our Renewing Mist and keeping as many up as we can by utilising our damage abilities. Abilities such as Rising Sun Kick, which is a key way to not only spread our renewing mists, but this also extends our casted Renewing Mist.
You should use Tiger Palm to get stacks of Teachings of the Monastery to reset our Rising Sun Kick cooldown, which can go a long way.
Also, Ancient Teachings will make our Rising Sun Kick / Blackout Kick / Tiger Palm heal someone within 30 yards, so maintaining our damage abilities in melee is extremely important.
