I've got 5 miners in the AC silver mine and they rarely ever get PK'd and since the 4331 patch broke COtobo and TQ changed the gem frequency in mines, I've only got 3 gems in about 3-4 weeks time, previously I would have gotten 30-50 gems in about 7-10 days.
Even if COtobo comes back, I don't think its worth mining anymore, what's everyone else experience with mining since the 4331 patch?
I think this is TQ's way of taking mining out of the game and thus fewer AFK players running will allow more non-AFK players on the sever before they need to split the server. Its all about the money.
