The legacy AI maps (like 6.72f) were infamous for their stupidity. Allies would walk into five enemies, never use BKB, or steal last hits. The 6.90 AI New engine fixes these pain points.

| Feature | 6.88 AI (Old) | 6.90 AI New | |---------|---------------|---------------| | Hero pool | 112 | 120+ | | Bot jungle | Rarely | Yes, efficient | | Item builds | Fixed | Dynamic (Manta vs BKB) | | Roshan AI | Only after 40 min | From 20 min | | Compatibility | WC3 1.26 | WC3 1.27–1.31 | | Lag/stutter | High in late game | Optimized |

The "new" AI uses a threat calculation model. If you are below 40% HP and visible on the minimap, two mid heroes will rotate to your lane via the river rune path.
