I don't know how much sense it actually makes since half the games i join don't have antagonists and i played like 8 hours yesterday, so yeah there is demand for Antagonists but it's not working for some reason.
Btw in those 8 hours i have only played as Antagonist 4 times ... and with those 4 times im ranked around #10 on the Antagonist board( i always queue Antagonist/raider at the same time) not many people are playing antagonist , you can actually count them in the ranking , theres alot of demand it's just not working like it should.
What i think it's not working is the system priority , if you are queue'ing both Ant/raider it should always prefere you as Antagonist , the odd thing is that raiders will pop faster and half the time there is no Antagonist while i was queue'ed Antagonist too.
