I wondered why the mode: Custom Battle is not used more frequently by me and other players.
And I found that its interface/window or UI is rather simple and none appealing.
The UI window to select from which Custom Battles to join, in SC, does not even display the ranks of ships needed to participate:

The window to create a custom battle in SC has only a very minimal set of options:

In comparison, for example, the only other game I have on my PC, The Battle for Wesnoth, has lots of switches and informations displayed in its UI window for creation of battles (with many tabs and second degree option subwindows):

The thing is, if the matchMaker (especially for PvP) really is a problem, why not try to avoid its limitations by letting the players do what they might can do best: create the battles they like.
Human players might be superior in self-organizing fair and satisfying battles. For that to happen, in SC, the UI windows for Custom Battles must be overhauled and reworked.
One could even imagine the benefits if the pro guys (like NASA, STORM) would do their ‘stuff’ in custom battles, exclusively (docked on imaginary future Station Fort Muerto in the middle of the galaxy map)!
