Making this change in ROA is like you are admitting that botting is legal. If you cannot touch those farming roa, (or toi, or all of the raid bosses, or catas) then you should change the game rules and say that botting is legal. Or at least add it as a vip10 bonus, since that seems to be the get out of jail card.
Also, not having cloths as a random reward but putting a fixed price is terrible even for your standards. You made it slightly cheaper than the rmt and it will have no impact on the in game price. And with what you have as rewards for the loot box, prices of the scrolls earned from the aden tour mini game will actually drop. Good job for that too.
