Change in Patch 3.11:
Custom Games
AFK detection reduced to 3 minutes (from 8)
- The game now kicks you at 5 minutes (previously 12 minutes)
A minimum number of human players must now participate in a custom game to receive IP/XP rewards. The current thresholds are:
- 5 players minimum for Summoner’s Rift, Crystal Scar, and Howling Abyss
- 3 players minimum for Twisted Treeline
- A notification has been added in the end of game results screen to explain why players did not receive IP/XP
For pricing of ref bots -- no idea.
