Seems to be bots r not that effective due to random spwning place, it would b small fraction of manual farming.

3x is really high, but it can help in enchantment along with that now some interesting gold sink can be brought like making PvE pets enchantment for PvE only ofc, just an idea.

I feel like something like 4th tier should be a regular map for maybe L30-50+ so that new comers can farm it for basic purposes and 3rd tier map can a premium regular map (for plat)
