🆕 New Feature: Import KoS from Spy (Classic / TBC / Wrath / MoP)

How it works:

⚠️ Retail 12.0.x (Midnight) API Restrictions – Important Notes
World of Warcraft Retail 12.0.x (Midnight / pre-expansion) introduced significant API restrictions that affect what addons are allowed to detect and automate.
As a result, some KillOnSight some features that existed in earlier versions are no longer technically possible on Retail.
What changed
Blizzard removed or restricted several APIs that addons previously relied on, including:
- Unfiltered combat log access
- Indirect detection of unseen or stealthed players
- Certain protected targeting behaviors during combat
These changes are enforced at the client level and cannot be bypassed by addons.
What this means for KillOnSight on 12.0.x
❌ Stealth detection
- KillOnSight cannot detect stealthed players on Retail 12.0.x
- This is not a bug — the required combat log signals no longer exist
- Stealth-related options have been fully removed from the UI to avoid confusion
✅ Nearby list now reflects visible enemies only
- Players appear in the Nearby list based on:
- Nameplates
- Target / mouseover interaction
- Disabled in BG's
There is no “radar” or hidden detection in Arena or Battleground and limited detection outside.
🆕 Import KoS from Spy (Midnight Only)
- Download offline importer KillOnSight-Spy-Importer.zip from here: Spy Importer
- Instructions on how to use are in the README
- All your KoS lists can be imported offline since spy no longer loads on Midnight
Summary
KillOnSight has been updated for Retail 12.0.x to:
- Respect Blizzard’s new API limits
- Remove non-functional or misleading features
- Focus on reliable, visible-enemy tracking and usability
If you remember features from older versions that are no longer present, this is due to Blizzard API changes, not addon abandonment or bugs.
