I'm going to give a fair analysis - Did 7 games with me duo at roughly plat 4-3 mmr and only won 4 and lost 3 (57% winrate), I don't believe he can boost reliably up to Diamond. But will still be able to rank up an account with a lot of played games.

I also feel the only reason we were able to win the other 4 was cause I was also able to solo win my lane taking pressure of his job, hence I must question how reliably he can boost.

All in all, he is a nice guy however compared to other boosters I've played with in the past.

I would say he can boost most likely up to low plat with 60 to 65% winrate, if thats reliable enough for you, then go ahead.

Thanks again for playing, good to always give new people a chance.
