What do JP players think of the Cruise Chaser mount?

[Sotaris]

I think they have increased the price of the sub, just not in the way that some would think. With the retainer service and companion app, some players are paying around $32 a month for a sub to this game. They just did it through incentives instead of an actual price hike.

That's one way to look at it but I think most of us can agree you don't need that many extra retainers, if any with proper inventory managment.
I have max retainers personally but I'm also a nutcase that utilize the retainers for gathering me materials plus im a hoarder and love crafting.

So i'm in the €20-25 area I'd imagine. I don't really pay attention at the exact amount but in that ballpark i'd guess.

and clearly the amount of subscribers hasn't increased either, right?

Yes it has, skyrocket since 2019 assumingly .
