I have reread the rules and I can't find any reference to "unbalanced AW investments". We had a player leave the game and they put hundreds of kp in to lower level players AW with no problem.Unbalanced AW investments are inhibited, but they have always been against the rules.
Do you have a guess on what fair is, 1 to 1 or even 2 to 1?...15 AW kp per shard if they do a fair swap with any other player.
I found the answers on the Beta forum. See below.
