About fair matchmaking

Was 8-2. Finished 9-8. Panth jungler gave every drake and barons to enemies (simply ignored us and was afk farming or standing still on midlane). Vlad was playing without Will Of Ancients (without any cdr items at all). Akali started fight when enemies had 5-drakes buff + baron. Wtf!? Another game I was playing agains Riven booster with 85-90% winrate.

Fair matchmaking? Pleeees I'm not believing in it anymore.
