Well, you have to use like 20-30 Loveca to get a second event SR in the JPN version and I don't think they will change their way of doing things for the ENG one.
Sure, the first Nico event had a rank cutoff at 5000 for the second SR, but it probably also had a lot more players spending money on the game, compared to the ENG version.
So what I'm trying to say is, they probably never raised and never will raise these cutoff points due to the overall number of players. Instead they probably raise it by Loveca spent on these additional SR tiers.
I remember a couple of months ago the JPN version got crazy cutoff points for the second SR. I'm talking about like 60 Loveca (for some people).
But now, like I said, it's back at 20-30 Loveca. So yeah, I guess the only thing "free players" are supposed to get, is that first SR.
I mean you could still get that second SR for your favorites, by saving up the free Loveca, but you will probably never be able to get them all without spending a bit of money every once in a while.
