new way of searching other people to attack

The searching process is to find another player to attack within the same league:
i think it should be based on level, due to people being able to control the amount of trophies you have, inwhich you could be getting attacked in silver league by someone who is over level 100, and get three star'd which isn't fair, i think the change
Should be that it searches for players who are either the same level as you, or at least 5 levels lower or higher than you, therefore this would make the game more fair and equal.
