If the rate isn't bad what I'm hoping is they turn the veteran reward system more into a Kupo Cash system, where they sometimes add stuff to the shop (like Cloud Outfit) but instead if you didn't like what they added you could buy that Slepninr mount or whatever else instead. Like a few Vet rewards I didn't dislike but just knew I wasn't going to touch, but in this system I'd still be happy because even if I don't spend it this second I might see something interesting down the line a bit (or know that one seasonal item I just got to have will come up soon).

The issue here is they might make the rate so bad it takes you two years to buy Slepninr, or they fall in love with the system so much there is a unique thing being added every week and they lose focus on the main game lol.

However if they can go at it reasonably (imo) then it could be quite nice. As theoretically it would encourage people to visit the shop, encouraging those who would spend money to spend money, those who would but thought it was too much could use the KC to supplement their purchases (making items feel less expensive sometimes), and those who never ever would spend money and loathe the shop would still be able to enjoy things from the shop (like exclusive mounts are no longer barred for these players, just need time subscribed and not to spend it on other things) - reducing the amount of hate they have for it (just be careful of consumables lol, in fact I still would love to see the dyes moved into a permanent tab).
