I agree with Obi-Two (no relation). I remember that post from the dev, and it's certainly proven true for Kenobi's Command.
A while ago, Pirate started a thread seeking all sorts of data, including base score medals, etc. Various squads placed their data there. I did too. We had a match up that conclusively proved it was only about base score.
I do think matchmaking has changed since then. Matchmaking seems to be taking longer for everyone. I think that' s because they've tightened the parameters (drastically loosened in April this year). I regard this as a very good thing. I'd much rather wait for a fair war than be instantly matched to an un-winnable one.
Since the Squad Wars servers went down, and the OP Imp GR-gate issue we've lost several long serving commanders. We now have a lower total base score for our War Parties and we've had nothing but fair matches since September.
If you want to track War Party data again, I suggest you resurrect his thread.

Stop by for Wars, perks and rep points. We're maxed out.
