1. Poor Matchmaking, Sometimes my teammates have high rune and opponent have low runes thus making an unfair match and sometimes reverse happens, opponent have high runes and my teammates have low runes resulting in unfair match. Rarely i encounter fair match. 2. A gold League player is sometimes matched against legendary League player. 3. Some heroes are overpowered. 4. Action against Abusive chat aren't taken unless reported. 5. Cross server matches are so laggy. Please improve such things.
