Placing new players too high.
OK, so check this out. The "higher" ranked players on our team were 6/9 and 2/14, (wins and losses) relatively new players to ranked and placed in high bronze. On the other team they had a combined 1000 or so matches on their 2 highest ranked players this season so they were probably ranked where they should be. If you look down the roster for both teams, the same team had all the most experienced players. Not surprisingly the match was a one sided stomping with our previously mentioned jungle shyv 2/14 placing a grand total of 3 wards.....
I don't see how placing new ranked players in low silver/high bronze when they are obviously not at that level and pitting them against players with hundreds of games each is making balanced matches. I have seen this far too often where the "high ranked" player on my team (or the other team) will have no ranked history and no clue, while their opponent has a few hundred or thousand ranked games under their belt.
