In case anyone else is wondering:
I don't know, apart from joining every month and getting some supplies, what c.o.r.e players can have high-quality content, except for the number of purchases, there are no other high-quality products? Then I can suggest that in addition to buying c.o.r.e to get cards, you may be able to add some things that ordinary players can’t get. For example: players who buy c.o.r.e can draw runes more easily, or tap invasion It will be easier to obtain a little more supplies than ordinary players. Maybe I suggest that many people will have opinions, but if you don’t do it like this, no one will want to join c.o.r.e. Since there is this discount, why don’t you pay more attention to it? What about this direction?
From this, a suggestion would be, why not make the auto pick up be a feature only available to CORE players.
But for just the extra 500 inventory space, it is worth it.
