The Mistweaver routine is functional but doesn't really use mana efficiently.
There are some weird things going on with the MW routine as sometimes even at full health it casts EM on self when really the tank needs it. It also needs to prioritize tanks more. The Surging Mist for Chi is a great addition but it needs a little more work, like only SM for Chi if someone is below like 98% or something. I think this is where the mana problem is. I currently heal better playing by hand but it is functional Dadunston.
I am awaiting 100% functionality though. For as many classes as this routine works for and with all the changes he is doing a great job progressing the routine for 100% of all the classes. All the classes do well, but there is a long road ahead for optimal healing routines.
I wish the UI was different though, and more organized. But once you get used to it and modify it the way you want it, it does well.
I don't like the Soothing Mist and Surging Mist settings though, wish there was more settings/modifications allowed. Overall there is no reason not use this routine over others. Singular does some great stuff with MW right now and I am preferring it over the premium version of this, but for classes like Holy Pally, I prefer this routine hands down.
Good Luck with furthering the routines!!! Cant wait until they are 100%
