Or perhaps BLM is rated that highly because it has the design philosophy that everyone wants for their own main job?
- Easy to understand and execute at the basic level (standard rotation)
- Has a high ceiling for optimisation (transpose lines)
- Forgiving enough to not have their entire rotation crumble on death or when they don't get full uptime for 2 minutes
- Has ways to overcome their weakness
- Rewards job and fight knowledge
