1. To anti-stuck stuck units.
2. To catch leaks from your partner lane.
3. In the middle-area (near the king).
Any other use of anti-stuck is illegal.
I want to urge people to report on the forum if they see any illegal anti-stuck action. In addition, I will randomly check replays over the coming weeks to check for anti-stuck abuse. If I find any abuse, disciplinary actions will follow.
I hope this isn't necessary

Happy gaming!
