EXP Chain Feature for MMORPGs

I was suggesting that for MMORPGs, that there should be an improvement for gaining EXP. It's called the EXP Chain, if you have more than one character on the same account on the same server with characters at level 10. Then, all your characters on one account, and one server will gain experience points. Players have the option to turn off the 'EXP Chain' if they just want to level up and give experience points to one character on one server and one account. This feature will not be added to free-to-play, and pay-to-win MMORPGs.
