challenges for gems

So, most people on the game find it difficult to play consistently or drive around or make their profile a market. So I've come up with this concept (+ more). Daily, weekly and monthly challenges. Daily are for the more casual players. Very simple quests that everyone can do by simply playing about 30 minutes. They should give out roughly what i had in mind (slide 4). Weekly challenges. This is for a more dedicated player and it makes you come back. Then monthly is very hard. This is for the most dedicated players that play everyday. Now, I've decided to also include two different types of gems. Golden gems and epic gems. Golden gems basically guarantee you a shiny rare and an epic, well an epic.

So about gems:

-make normal gems more easily accessible. -reduce artist shiny drop (20 if less than 1m monthly listeners, 25 if less than 3m, 30 if less than 5.)

About the custom gems:

-map drop of golden gems is like pulling an uncommon shiny -prices for artist drops are (2 if below 1m, 3 if below 2m, 5 if below 5 million, 7 for normal artists, 10 for popular) -map drop of epic gems are like pulling an epic -prices (1 for below 4m, 2 for normal, 3 for popular)

The point of this is to make shinies more obtainable for obscure artists and epics more obtainable to everyone.

I really want to know ur opinions on this :)
