It seems it's really paid focused and I don't see something like reroll gacha. I hope they will just delay it for .5 anniversary and not cancel it. It would be a real shame.

I guess the Beginner Pack is worth it for beginners if they want to spend some money. 200 Gems and 3 free rainbows is nice.
I don't know what gold gacha is. If it's free, it will be an okay source of R-medals at least.
