In a few months, we will all have full drone upgrades, eventually all weapons and armor we want, overabundance of materials, and it'll all be about capturing and fusing etc., getting best stats and holo illuvials..
So Solon tends to zero, eventually, while hyperion will always be 10000x more valuable... and crypton will always be the same, i guess, until we dont even care much about capturing and want to focus on the arena, for example...
