What ward placement provides the most comprehensive early warning of an enemy rotation towards the gold lane?

The ward placement that provides the most comprehensive early warning of an enemy rotation towards the gold lane is a deep ward positioned in the river bush closest to the mid lane, specifically on the opposite side of the map from the gold lane. This ward placement offers multiple benefits. First, it detects rotations from the mid lane, which is a common pathway for enemy heroes to move towards the gold lane for ganks or turret dives. Second, it provides vision of the enemy jungler as they move through the river, allowing the gold laner to anticipate potential ganks from that direction. Third, it offers early warning of support heroes rotating from the roam position. By placing the ward deep in the river bush, you gain vision of enemy heroes before they can enter the jungle or river area directly adjacent to the gold lane, providing ample time for the gold laner to react and position themselves safely. This early detection is crucial for preventing successful ganks and maintaining lane dominance. A ward placed closer to the gold lane offers less warning and allows the enemy to close the distance more quickly, making it more difficult to react effectively. This specific river bush ward is also relatively safe to place, as it is not directly within the enemy's lane and can be placed quickly while the gold laner is clearing minions near their turret.
