Read pages 7 and 8. Posted images. Don't trade with this guy lol. http://www.elitepvpers.com/forum/league-legends-trading/3153534-blackhawk-boosting-all-way-diamond-1-cheap-fast-na-euw-eu-east-8.html
Just for any potential buyers. He can and does boost amazingly. I was silver 5 now currently in Silver 2. He has never lost my promos for me (always gets 2/3 wins, without having to redo it). Wins around 7-8/10 games easy. Carries hard every game no matter what role.
Bought S2 to G5 boosting. Gave him my account at 100 LP with no promo games played. Then his booster proceeded to lose 5 out of 7 games and got me down to 50 LP. He will not refund or reply to my messages.
DO NOT DO BUSINESS WITH THIS GUY.
Fastest and cheapest elo-boosting service so far. They did the job in less than 30h for a real low price. Chat-Support is as fast and nice as possible. Blackhawk is really patient and the boosters are well trained. I believe they win around 90-95% of their games in Bron/Silv/Gold/Plat. Payment was done without any greater circumstances.
Big + for this service! Recommended!
