I think most of us would agree that most of the botting was done by RMT, and to combat that they changed the drops into R/Ex. I was a fan of that, and if they continue that in this game then I'm for open world NMs.
Most botting was done by HNMLS & real players, not RMT.. I don't know how long you played XI, or what your experiances were, but I can promise you this, especially as the years wore on and it became even more widespread.
Long ago there used to be drama about who was botting.. As a sign of how things have gotten, people largely don't care anymore, and many admit that their LS bots. The response is often "Yeah we bot, try to beat us," instead of denial. This just showing how when something completely permeates a playerbase, that it will eventually become more acceptable.
