This feature was introduced a long time ago. What was happening is that a powerful player would kill the defence and a low player would kill the base, thus gaining the resources and growing faster.
This is a feature that was introduced to prevent 'gameplay' that wasn't intended. Raising the complaint with support will be a wasted effort. Traditionally support reply (if they do) that they don't support the game - and as it is an intended feature introduced a while ago, it is highly unlikely to change.
