The matchmaking is utter pathetic. My last game has had a Thrall in who when killing the terrors to drop seeds stood in his stun every single time. He simply never got the concept of moving away before it hits. He also proceeded to run in solo when outnumbered everytime.
Also a Li Li who thought when a team fight was happening, that being stuck in the middle lane soloing is a good idea.
A Falstead in the wrong place more often than not.
3 games before that had an afk and a bot, granted not matchmaking but still annoying.
Just had another game, highest on the team bar me was level 30, rest were under or early 20s. Checked opposition, all 40 and some with around 700 games.
The balance is beautiful.
