same thought as pickwick
The systems in place only prevent botting.
Because when you think about it this is a very good system they developed.
I did not bot or anything, but if I were involved in that I would do it as follows and Im pretty sure the long term experience of those bots and their networks came to the same working order I explain below:
Now imagine a network of bots or lets call them suppliers. They farm all kinds of stuff, but they don’t sell it they have no time for that they just want to dump it and get right back to farming.
So lets say 10 bots deliver their goods to another character who is going to sell all that to players or on the market.
That already is one trade.
In Tos now that bot Seller can no longer sell the materials and normal items have their potential decreased. The potential to become a powerful +15 weapon is practically zero when you take into account that you would want 2 sockets. Then 1 potential is a huge deal.
And with mats its even MORE important.
Imagine a bot army specifically farm just a particular mob to sell these mats. They now have to do it individually. They cant go through the seller anymore.
Especially the mat restriction on this one is very good for a normal player. If you decide to farm a specific material to get a decent price for it you can. WITHOUT competing against a network that basically controls the prices.
At least thats what I think they try to achieve with this restriction.
And yes, we need those restrictions.
