Just make them obtainable through the shop again or make crate keys about 150x more obtainable
why? because a few people were able to stockpile 30+ igs just from the shop selling them for 100k/per before you guys removed it
at 1 crate a week, and ig drop rate at 0.5%, it would average 200 weeks or 3.97 years just to "earn" an ig (it's not even earning since you did nothing to gain that key but log in weekly)
even adding in the new monthly bonus of 5/month that only adds 1.22 keys/week or just over double what we already earn in a week. This would lower the expected time to 97-98 weeks, just under 2 years.
The system is asinine and not thought out as well.
