I don't think this world was planned on going on very long.
There are really not any large changes except for the mining overhaul.
I do hope this world becomes interesting though

. World 3 was quiet for 98% of the time.
and I agree with Rye's point that nerfing things in the middle of the game hurts, almost every one of his points I have been affected by as well.
Table nerf, Sling nerf, MM nerf, and this nerf.
People know they can catch up which si why they start investing in, say, MM. Nerfing it won't just hurt the players who were archers to start with, but also those who have been working towards raising their MM for so long.
I agree that nerfing stuff at the end of each world is hard, but nerfing it in the middle is just aggravating. Although concerning this particular nerf, it was done early on enough to not cause too much damage so I don't see why everyone is whining.
