Either way, yes — but…
Let’s say whales stop RMT-ing and buys these P2W sh!t instead. They’ll still need a huge amount of silver for leveling attributes so they’re prompted to sell some of the stuff they’ve gotten from these gatcha cubes for ez silver. Let’s also not forget that they can also still farm silver for themselves and have the luxury to solely spend those silver on attributes.
But as @SlyGoat shared, if this does affect bots in our version in terms of ROI they will just move on to another MMO. That means no bots farming silver for players to sink into their attributes.
This leaves the non-whales to do the dirty job of silver-farming to buy the stuff whales are selling which really isn’t very efficient for them overall since they also have their own attributes to level - BUT they are still “forced” to spend silver in buying those stuff or else they’ll be at a disadvantage equipment-wise unless of course they don’t give a sh!t about being behind everyone else.
TLDR once botters are gone…
Whales can easily max attributes and have uber equips.
Non-whales will significantly lag behind in terms of attribute levels and equipment uberness.
