Someone posted a video on reddit of a real world player doing what is basically the LT move. I'm not saying that validates it though. I don't like this being used in our game. While it can be defended, it's obviously very frustrating to deal with. It's a known issue that isn't easily resolved or it would have been by now. However, it's not something we'd consider a cheat so it's not an actionable offense. Also, there is no speed gain. You aren't losing speed as you should be, but you're not gaining speed or getting a boost.
As far as I know, a bot will replace a human skater when they disconnect, but will still control their player until the next stoppage. I assume that wasn't the case here and this player model stayed in the game? If it is a glitch, I really don't think it's one being exploited. I'll pass on the video. Thanks for getting a clip.
