So, after a few months, and the result i said it would happen, im here again to say the same thing.
The only way to illuvium overworld to have success, is to remove all costs to play the game on all stages, but you'll only find T0 on all stages, and in some ultra rare cases, you'll find a T1 - T5 materials / illuvials
This way, all free to play players will come back again to play the game and try their luck finding rare stuff, the ongoing illuvials/materials will push in price
I got downvoted when i said this, lets see now, after months, what is your opinion?
Happy with the results of Overworld?
