Gacha, loot boxes and alternatives?

One day if it were declared that having too much RNG systems with money inside a game is not good then the question becomes what is there to do about it? Is the right avenue to adjust the money mechanics themselves or to reorganize other parts of a game? How much Pay 2 win is acceptable? At what point does a Pay wall become too big? If a game like Maplestory wanted to do a large overhaul then what could be other alternatives to depending on RNG?

Paying repeatedly for consumables to stay ahead of expirations and decay.
