Recently lost my HC Seasonal Demon Hunter to a 92xx lag spike on Grift 30, not sure if there's rules forbidding asking for someone to help me power level up a new toon so I can get back into competing for spots while my team sleeps, I have to pull an all nighter to catch up to them with any hopes, and I don't have my gem of ease leveled to 25 yet. If this isn't allowed, I apologize for asking.
There's an GotBoostedHC community on the EU part of Diablo. I'd suggest you go there and ask in-game. I have been seeing quite a lot of people asking for a boost there and considering how fast people are gearing up, I'm guessing that there is a high chance you'll find a booster.
