I for one hate this instance patch hotfix.
I use one account to raid/have a farming character for mats.
Most of my income is from because able to get mats from dungeons to avoid the open world botters, i.e. herb campers.
All this is going to do is make botters make more accounts and spread out their farming strategy. It just punishes me by having to limit what dungeons I farm for herbs and also raid. And on popular servers they will just make more accounts potentially creating a log in queue situation for high pop. servers. I understand you are trying to crack down, but do it a different way.
