K.T.H. (Kill The Healer)

There is one truth that every PvPer must face in any game they play: healers must die. This add-on helps you identify and mark healers on both sides so your team can focus targets effectively in PvP.

K.T.H. is a modernized fork of H.H.T.D. (Healers Have To Die) by John Wellesz, rebuilt for WoW 12.0 (Midnight).

WoW 12.0 introduced "secret values" in instanced PvP: enemy player names and GUIDs are no longer accessible to add-ons. K.T.H. works around this by using Class + PowerType + DPS-power-exclusion matching on nameplates, cross-referenced against scoreboard data.

Current features:

Automatically places healer indicators above player nameplates in PvP battlegrounds and arenas. Friendly healers are identified by name via the scoreboard; enemy healers are identified by class, power type, and DPS-power-exclusion (so Ret Paladins, Shadow Priests, etc. are filtered out).
Separate indicator icons and colors for friendly vs enemy healers. Both are fully customizable through the in-game settings panel or slash commands.
Multiple icon presets: cross, skull, star, circle, diamond, triangle, moon, and square (all standard raid-target icons with custom vertex coloring).
Adjustable Y-offset and indicator size so you can position the marker exactly where you want it relative to the nameplate.
Inherits H.H.T.D.'s announcer module for posting healer lists to raid chat, sound alerts on healer mouse-over/targeting, and friendly-healer-under-attack warnings.
Custom marks module: apply persistent personal markers to any unit's nameplate (visible only to you, persists across sessions).
Integrates with the DebugLog add-on for diagnostic output. Toggle diagnostics with /kthdebug or run a one-shot dump with /kthdiag. All diagnostic data is routed to DebugLog's scrollable viewer instead of cluttering your chat.

IMPORTANT: You must enable nameplates or you will not see any healer indicators!

How it works (Midnight / WoW 12.0)

In WoW 12.0 instanced PvP, UnitName() and UnitGUID() return secret values for enemy players. K.T.H. uses a multi-strategy approach:

Scoreboard scan: C_PvP.GetScoreInfo() provides each player's name, class, and talent spec. K.T.H. identifies which players are healers and tracks them by name (for friendlies) and by class (for enemies).
Nameplate matching (friendly): Friendly names are still accessible, so K.T.H. matches friendly nameplates directly against the scoreboard.
Nameplate matching (enemy): UnitClass() and UnitPowerType() remain accessible on enemy nameplates even when names are secret. K.T.H. checks:
- Is the class healer-capable? (Priest, Paladin, Druid, Shaman, Monk, Evoker)
- Does the scoreboard confirm an enemy healer of that class?
- Is the unit's primary power type Mana?
- Does the unit lack DPS-exclusive power resources? (e.g. Holy Power for Ret/Prot Paladin, Insanity for Shadow Priest, Astral Power for Balance Druid, Maelstrom for Ele/Enh Shaman, Energy for Windwalker/Brewmaster Monk)
Only if all four conditions are met is the unit marked as a healer.

K.T.H. is built on the H.H.T.D. framework by John Wellesz (2072productions.com). The original add-on provided healer detection via combat log events, nameplate hooking, and the announcer/custom-marks modules. K.T.H. adapts this for WoW 12.0's secret-value system with a new nameplate indicator engine and scoreboard-based healer identification.
