We don't reset just based on one or seven players complaints? Do you have legit proof? A video? Or do you just have a picture of a new player with many losses? I have like 15 losses and 3 wins on my ipod, does that mean I boosted someone?
Also this brings up a good point, in MY opinion, spar stats mean nothing on era. Been saying it for a year, you can have the stats but not the skill to back it up. Why? Because you can reset and just spar when only noobs are in the room, and if you lose just reset again. This also makes resetting by staff not really effective or an "I don't care effect". I doubt someone would be stupid enough to risk boosting, getting caught and reset and losing their legit wins in the process.
If you can provide actual evidence against duke other than he sparred a new player multiple times, then do so. Otherwise, who hasn't taken advantage of the fact a new player is getting used to the game and getting in a few wins? Also I would love to see that 1000-10 stats you are talking about.
Also those people that do care about stats will try and get better at spar and continue practicing, simply because it is shown on the account. I wouldn't want to walk around with 0 wins 200 losses, so I would train and get my wins up. It separates the lazy from the dedicated imo.
