you forget to notify the client that matches in specific mod/category are not found and ask him to continue search or not, which he can continue to wait for waiting +x cycle time more again and again

if you don't ask him if he wants to continue to wait for specific prefference, meaning if not found it becomes irrelevant, you are basically begging for this block to be removed.




you can argue and debate what can be added, but i would like to remind that instead of adding useless stuff matchmaking should be focused on streamlining everything in order to minimize waiting for matchup.

if implemented streamlined system will prove to be reliable - it can be expanded later, but right now we are talking about adding lots on unnecessary stuff on top of something non-existant yet.
