This is not the sale of an already existing account. This is the sale of me playing your account to boost your statistics. Stats include MMR, PSR, and KDR.
I'm a very reputable player in the HoN community, this is a legit deal. If you post your account name here or PM it to me, I will message you in game and negotiate a price along with what specific stat(s) you're wanting me to boost.
The price will depend on how much of a boost you're wanting, and of what stat.
Also, if lessons are of interest to some, I'll consider doing that for a reasonable price.
