My understanding is that all DLC for Anthem will be free, so the pay more piece is a bit moot - with exception of course to the cosmetics microtransaction store that is a staple in these games these days.
I think the Origin/EA Access early release hurts these reviews a lot more than it helps them. There is a massive "day 1" patch coming this Friday that addresses a lot of issues that have had an impact on the reviews that didn't need to without the early access.
I myself am enjoying the game, but definitely question its staying power.
That's a very weak excuse when you have f2p games with free content updates and free dlc.
