Revise criteria in order to get into ranked games.

Most of us have probably encountered this situation more often than not whereby unskilled player or "trolls" join a ranked game and ruin the entire experience for the rest of team.

There must be a better way to ensure that unskilled or troll players can be weeded out. The current criteria of having 16 champs and level 30 doesn't seem to suffice.

Some ideas that came up were:

1. 500 total wins in 5v5 normal games
2. 10 champions must have more than 50 wins each

Poll Question: do you think the current criteria in order to get into ranked games should be revised ?

Thanks silent
