Sure, interesting thought. You’re right in that I suppose I was thinking of it as a checklist after you’d already made a build - “Here’s my build concept, now, have I dotted all of my 'i’s and crossed my 't’s ? Let’s see. Oh whoops, my attack speed is low and I’m using weapon damage. Mkay.”
That said, it could be fun to create a second chart or an app walk-through or something that resembles
this flowchart , but without pointing to specific builds, just specific considerations.
ie: first question:
Tank
Melee
Ranged ** select ranged **
Caster
Second question:
Dual wield
Pistol + Shield
2h Ranged ?
(etc etc). Then you’d really be getting into creating a “CharacterBuilder” type of app or something, where at the end of that it recommends things like “Runebinder set”, “Harbinger set”, “Valduun’s Set” or “Shaman class” for 2h ranged and so on.
While that would likely be more useful for newer players, I feel like that’d be a much, much more detailed tree that I don’t think I have time to flesh out 
But I’d happily contribute thoughts if someone else was taking lead on it?
I assume in the chart Heal Procs also includes skills like Pneumatic Burst, Word or Renewal, etc?
Yes, that’s what I was thinking 
Anything from Healing Rain to Blood of Dreeg or Wendigo Totem or Augur’s gloves or set bonus and so on.
