I would like to suggest the possibility of adding a "Reset all Stats" option.
I have been watching the amount of threads generated in the forums concerning people who are annoyed with the tier system. (Being bumped up into T4) Myself included. Well I thought about it, and this is all I could come up with for the moment. If you could reset your whole account, So you start from scratch again. I think it would definitely reduce the amount of new accounts created.
Just an idea....
