A game can be enjoyed regardless of how much you may currently hate it. It is simply because your love for the game in its prime subsconsciously outweighs it.
NX transfer issues aside, the stamps themselves aren't even transferable between characters via storage. I literally have stamps scattered across all my characters exactly because of your second point.
Nexon seemed to uncap the 10 coin limit and then put the cap back on randomly. They need to make it more conspicuous on their pages like you've stated with the ninja patches. I have to painstakingly go to forums and look around to make sure there were actually nerfs and changes that weren't mentioned on the official pages. Their patch notes for the Shining Santa Boxes still say 1-5 V coins, but the most you get is 3 as far as I know... What's the point of getting 3+ coins by chance from one box if there's a cap anyway?
Also the spell traces stopped coming for my Hi-V boxes after opening like 200 of them. The chances of getting that was already low, along with the hammers/scrolls...
