"[color="#1c2837"][color="#1c2837"]The experience that you have invested into a player is only permanently theirs once they can match it. Until they match it, it is only theirs so long as the connection stays intact. The surplus on either side would be taken if the link is disbanded and given to the new player that is linked to."
That would lead to trading, threats and trolling as well ("I will take away your EXP unless you do X", "Hey, I'll pay you X gold if you help me rack up Y EXP so I can sell it on eBay to someone else"). Where there is a way, there are always those that will do anything in their power to f*ck the game inside out. The thing is, will it be a minority or mayority.
