There are plenty of things that cannot be automated presumably?
You are likely coming at this from a perspective of the standard clients. Unfortunately, this is the wrong presumption. Anything I can think of that's been added to the game to prevent automation has always ended up only hurting legitimate players and gets automated anyways, all while making it more of a grind or more annoying to legitimate players (in one way or another) that even try the activity. Guess who doesn't care if things are annoying or a grind? A program running 24/7.
- The devs thought they were clever, randomizing ore/wood. Only ended up discouraging legitimate resource collection.
- The devs thought they were clever, releasing the slims veil as a rare reward from trade routes. Only ended up as a botting payday.
- The devs thought they were clever, releasing a rare Hiryu as a reward for the Eodon quest. Only ended up as a botting payday.
- The devs thought they were clever, releasing the Yukio earrings as a rare quest reward. Only ended up as a botting payday.
- The devs thought they were clever, mixing it up this year with 5 minutes to get to a random coordinate to kill the manifestation. Until the ToT was released 90% of the people at the manifestation on Atlantic were bots.
- The devs maybe thought they were clever, mixing up the ToT in random towns because they didn't realize the power of these clients. Yea, ToTs have always been a bot payday, as often gloated about in the discords.
Without getting in to details, the cheat clients have built in features that allow you to do every and anything. For example, look at these ToT sampire bots:
- Fully automated, running 24/7
- Auto relog/login
- Auto run back and forth at a town crier, awaiting a new town
- Auto travel using vet teleporters at Nabin's ATL house
- Auto repair gear using public and private repair benches
- Auto turn in point items
- Auto claim rewards
- Auto stash rewards at a loot house
- Auto res if dead
- Wouldn't be surprised if auto put point items/reward items on vendor
- etc etc.
These bots are so complex they are able to press play and not even be looked at until the event is over, ~90 days from start to finish. One click will farm likely 100k items easily per character over the course of the event. That's why these clients are so dangerous to the game. Tools that existed in the past were not this powerful.
There are also, presumably again plenty of ways of preventing items being abused within the game system for either selling or the like, by either making certain items account bound when equipped or the like.
The only idea I've ever seen suggested that would actually work to completely curb RMT botting without massively punishing legitimate players, an idea that other MMOs have implemented to solve such problems, is 'account bound' items. And honestly, these items are so powerful they shouldn't be handed out like candy that they are, my opinion of course. That would include everything from points to all rewards - anything gained from the event. If you have another suggestion I'd like to hear it!
