How to avoid Bots becoming required again to experiance endgame content in FFXI.
Don't add new world spawn HNMs with good drops that are not obtainable anywhere else, or are vastly easier to get through camping these new HNMs.
Part 1.
Nothing anyone can do can actually prevent the creating or use of bots in any MMO, except not adding content that can be botted. The only way to avoid bots becoming required again is to simply instance all HNMs in raids like Aurum Vale or Cutter's Cry in FFXIV or in the world similar to how Voidwatch is done. Adding free roaming and spawning NMs (like Kings use to be, or how Tiamat, Dark Ixion, Cerberus, Sandworm, etc are right now) with good drops will only cause the complete revival of bots.
