CombatCalc

 CombatCalc adds a simple tooltip that shows your odds of winning against any mob you mouse over.

  How it works:
  - Every time you fight a creature, the addon records the outcome
  - The more you fight a specific mob type, the more accurate your predictions become
  - First time seeing a mob? You'll get a rough estimate based on level difference and whether it's elite/rare

  What you'll see on tooltips:
  - Win chance percentage
  - Threat level rating
  - Your personal kill record against that creature (wins-losses)

  Class Immersion:
  Every class sees different terminology. Warriors get a "Battle Record" with "Victory Odds", Mages see an "Arcane Bestiary" with "Calculated Odds", Rogues have a "Mark Dossier" - you get the idea.

  Commands:
  - /cc toggle - Enable/disable
  - /cc estimate - Toggle initial guesses for unknown mobs (disable for true Hardcore experience)
  - /cc stats - View your overall stats
  - /cc search <name> - Look up a specific creature
