Not sure anyone is defending the system in its entirety, but most of the suggestions in this (and hundreds of other) thread(s) are either clearly flawed or a return to what we used to have which is definitely worse than what we have now.
I do agree something should be done about small accounts who have just unlocked GAC facing huge accounts that sporadically bother to participate in GAC. But I don’t agree with any suggestion to return to GP based matchmaking or considering # of GLs or anything like that.
If solving one issue returns us to where we were, they shouldn’t bother solving it.
