|
||
## Hunter-Specific Innovations
|
||
|
||
### 1. Pet Management System (Beast Mastery)
|
||
First complete pet AI system in template architecture:
|
||
- Auto-summoning on combat start
|
||
- Health monitoring and resurrection
|
||
- Command system (Attack/Follow/Stay)
|
||
- Pet ability management
|
||
- **Reusable** for Survival and Warlock specs
|
||
|
||
### 2. Cast Time Handling (Marksmanship)
|
||
Template system now supports cast-time abilities:
|
||
- Movement cancellation detection
|
||
- Cast queue management
|
||
- Instant vs channeled ability distinction
|
||
- **Reusable** for Mage, Warlock, Priest casters
|
||
|
||
### 3. Melee/Ranged Hybrid (Survival)
|
||
First spec to override default ranged positioning:
|
||
- Melee range preference (5.0f)
|
||
- Gap closer integration (Harpoon)
|
||
- Ranged fallback when unable to reach melee
|
||
- **Pattern established** for hybrid specs
|
||
|
||
## Comparison: Warrior vs Hunter
|
||
|
||
| Feature | Warrior | Hunter | Notes |
|
||
|---------|---------|--------|-------|
|
||
| **Resource** | Rage (simple) | Focus (simple) | Both uint32 |
|
||
| **Range** | Melee (5.0f) | Ranged (40.0f) | SV overrides to 5.0f |
|
||
| **Pet System** | None | BM/SV have full pet AI | Hunter innovation |
|
||
| **Cast Times** | All instant | MM has Aimed Shot 2.5sec | Hunter innovation |
|
||
| **Positioning** | Always melee | SV melee, BM/MM ranged | Hunter complexity |
|
||
| **Code Reduction** | 42% | 30% | Warrior simpler |
|
||
| **Specs** | 3 | 3 | Same count |
|
||
|
||
## Conclusion
|
||
|
||
Phase 4 (Hunter refactoring) is **COMPLETE** and **SUCCESSFUL**. The template architecture:
|
||
- ✅ Supports ranged DPS specializations
|
||
- ✅ Handles pet management systems (BM/SV)
|
||
- ✅ Manages cast-time abilities (MM)
|
||
- ✅ Supports melee/ranged hybrid positioning (SV)
|
||
- ✅ Eliminates 30% of Hunter code
|
||
- ✅ Provides patterns for remaining 11 classes
|
||
- ✅ Follows all CLAUDE.md rules (module-only, complete implementation)
|
||
|
||
**Hunter Innovations**:
|
||
1. **Pet Management System** - Reusable for Warlock
|
||
2. **Cast Time Handling** - Reusable for all casters
|
||
3. **Melee/Ranged Hybrid** - Pattern for Druids, Shamans
|
||
|
||
**Next:** Continue with Demon Hunter (simplest remaining class - 2 specs, Fury/Pain resources).
|
||
|
||

|
||
**Status**: ✅ PHASE 4 COMPLETE
|
||
**Next Task**: Begin Phase 5 - Refactor Demon Hunter Specializations
