Let me explain to you why any policy that has a bot limit of 2 or 3 per player is misguided with a simple illustration.
Assume there is a policy of 3 bots per player.
Say we have 3 players, Player A, B, and C. And each has 3 chars.
So assume Player A, B, and C are zoning together, so they have a 9-man group.
Assume Player A is the group leader. Maybe Player B needs to go to dinner, and Player C has to put his kid to bed. Both Player B and C want their character development to continue, ie, gain rank, experience, levels. So they both say, "just recall and rent my chars when done."
Player A is now leading a 9-man group solo.
This is why if there is a pro-bot policy, I strongly recommend no limitations on the number of bots per player. The scenarios like I illustrated above will occur quite frequently and will be difficult to police.
People who play together frequently like clanmates will likely standardize on a common scripting codebase, furthering the blurring of dilineation of chars per player.
Arctic and its players can adapt and police itself without any imm intervention. Both dele and BiA were able to adapt to my army.
Most of the recent cases of imm intervention I can recall have resulted in players leaving the game and moving on.
