So far so good. He took a couple days off the boosting because he said he's having exams and for Victory day but right now he's at 100 LP with 1 win more to go for Plat 2, technically a day's time of work put into it. ^^
EDIT: He finished the boost now and yet again carried the game. 3rd time I've ordered a boost with this guy and I definitely recommend him 'cause he does an amazing job at the game.
