Step 1:
I'd change this to 1 crystal per zone, honestly. Yeah this step is skipable, but the i80->i90 relic encouraged people to get all the classes to 50 for titles and easy end-game weapons. I think having a fairly easy i200 would encourage people to try out more classes and considering the changes the jobs went through from 50->60, I think it'd be worth it to make this step a bit easier for the sake of having people try out the new jobs and differences in existing ones.

Step 2:
I'd keep this the same.

Step 3:
Since SE doesn't want us to get the relic in one day (which is understandable), I'd keep that idea but make it a bit easier.

I'd add the rewards to Roulettes. To get your relic you need to run each roulette 14 times (so two weeks if you do them all 8 in one day) or longer if you can only do 1-2 a day. This way no one could "rush" their relic and at the same time it's still friendly to those who are more casual and have a heavy work schedule/busy household. And then when the nerf comes (which happens when the next relic step comes out), just put it at 7 instead of 14.

And I'd also put the stupid items in the Key Items menu and make them un-sellable so they don't take up inv space and people stop QQing Idyllshire about how they accidentally sold them.
