So you put a strict limit on sparks because you wanted to stop botters endlessly farming sparks and dumping gil into the economy which caused massive inflation, I think the limit is too low but ultimately it was a good idea.
However, now those bots are just botting other things in an unlimited fashion and ruining the market there for legit farmers.
Why is there unlimited access to dynamis or Salvage now?
In theory this sounds good, someone working on something can farm farm farm right?. In reality a living human is not going to do more than 5-10 runs a day, even hardcore people are not going to do more than 10. So why not cap it at a sensible number when you know bots are going to do it 22 hours a day (and then 2 hours doing assault)?
I don't like putting limits on stuff but bots destroy the market for people who farm these things to make gil and if you're going to start putting limits on things that don't impact other farmers (sparks nerf) then you need to carry on down the chain to fix the issues that cause in other areas that directly do input other sellers.
