1.0.0 — First release

Healing Efficiency Lab is now available. This first version includes everything below.

Supported healers
- Holy Priest, Discipline Priest, Restoration Shaman, Restoration Druid, Preservation Evoker, Holy Paladin and Mistweaver Monk

What it does
- Reads your live character — stats, ratings, talents and each spell's tooltip — and works out what actually restores the most health for your setup. Nothing is hardcoded, and if a value cannot be read it says why instead of showing a fake number.
- Shows useful healing, or damage prevented, per second, plus overheal and waste, and roughly how long your mana lasts at that pace.
- Tells you which stat is strongest per point right now, with the full ranking, and whether it stays strongest for small, medium and large gains.
- Recommends a cast order for the role and damage profile you choose.

Plan and compare
- Roles: General, Tank and AoE Healing. Damage profiles: Low Pressure for a realistic demand, or High Pressure as a worst-case stress test to separate gear.
- Healing Test lets you see every spell's result and edit your own cast order.
- Toggle the supported planned talents and read the effect through Compare Gear.
- Save a snapshot, swap gear or talents, and read the exact current-minus-saved difference across up to five named slots.
- A Learn page explains, in plain language, exactly what each spec models, assumes and leaves out.

Good to know
- Open it with /helab. It is a planning tool and hides while you are in combat.
- It models you as the only healer, so results are an optimistic ceiling for healing and a minimum for overheal.
