I've made a "living" UI for my demon hunter.
Its made by using ElvUI, WeakAuras 2 and AddOnSkins.
My WeakAura strings:
DH Havoc Actionbar - https://wago.io/HJSigK0nM
DH Havoc Active Buffs - https://wago.io/rkPWfKRhz
DH Cooldowns (DPS) - https://wago.io/rkrjzYR2M
DH Cooldowns (Defensive) - https://wago.io/HJj17YR2G
