Pre level 30 has 0 balanced fair games.
Not even counting all the smurfs and level 30's running around making it unfun, the basic runes/masteries system it utterly ridiculous that high level players have inherent passive bonuses that make them stronger regardless of champ or skill. It is DELIBERATELY making in imbalanced that some other guy is way stronger from the get go. 100% of games, and I am not even exaggerating here are stomps and toxic, 100%. It's a total joke.
