While I can't wait for the update itself and I find the milestones very interesting, I think it's a bit dissapointing that the game will double down on those godforsaken meowing lootboxes. I mean, don't get me wrong, there's nothing wrong with a little excitement. However, you shouldn't lock individual items and rewards behind pure RNG, with no other predictable way of obtaining them. Even the current catsacks are ridiculous. I'd rather buy and trade in a thousand silvers for a cosmic than open another one, only to get yet another burning crab.
Heck, I'd take a party crab at this point. (and can we talk about how dumb some of the rewards actually are? Here's a crab with a special effect slapped on top of it. That's your second-to-most rare drop!)
