The loophole that lets the cheaters scan the whole map, is because all illuvials are determined when the map loads. We can combat this by NOT determining illuvials from the start.
Solution: the illuvials are determined AFTER they are shot down and the blue encounter rift appears.
The downside, we won't know what the rarest illuvial is just by looking from the overworld (just like early pre-season 1).
but it would encourage player not to ignore 95% of all low rarity illuvials, and actually chase, shoot, and fight them (fight is free now)
i believe rare illuvials should be minted not just with money, but also time, effort and luck. currently we just need 10 minutes and 10k crypton+salon to find a stage 3.
