I dont know if someone already talked about this but I suggest that Pim-keys and Amazing furni keys should be added on Spinner. Its fine if the chance of getting it is same as the chance of getting cats and ECs, just include it there. So boxes wont be just a collection for some players who cant/refused to spend real money here.
There's already 50 ec in the spinner. Given that you suggest that the chance to get the keys could be same as the ec, how would that make a difference?
For more chances I guess? And also to be a direct use for boxes instead of being an option for other things like Changing names, gifting premium items, etc. Im not sure, I know this is just an opinion/suggestion that would be neglected anyway but some of us in the community are secretly hoping for this little impossible change
