I really don't see how this is a good idea.

Like what Knuckles said, the stats actually DO matters if you want to prove someone you're a legit sparrer and not some booster.
Even RecurveZ has 30k+ loses to 100k wins (estimation is not needed).

There's a reason why you chose to reset it at the first place.

The sparrers with lots of stats would obviously like this idea because they've been one of those people who carelessly reset themselves and then asks for the stats back when a new reward arrives.
