With the new combat system, many tougher creatures including mammoths and trolls have become more or less impossible to hunt alone. I think that this is actually a good thing to encourage team hunting, but the problem is that in order to successfully hunt in a group in a game like this, the group must have at least one tank; someone who can take a lot of damage but usually doesn't deal much in return. Without a tank, there's a good chance that at least one of the group will die, which isn't a good thing in a game like this. The problem is that currently, no armour exists that can allow characters to tank in this game.
This problem reminded me of an idea I had a while back, about different types of shields. I always found is kind of strange that this game only had one type of shield; which seems to be a wooden round shield. One type of shield that would be perfect for tanking would be the kite shield. I don't have any pictures, but it's basically shaped like an upside pentagon, covered in metal. They are big, clumsy and used primarily to cover up the whole body to prevent any attacks from hitting the user. I was thinking that they could be added with a very high defence bonus, but they would also reduce agility by a significant amount, enough so that the amount of damage done versus damage received remains the same, but it still makes the user harder to defeat. This way it would be pretty useless in a one on one fight, so it would only be useful when fighting as a group.
It would be made from steel, wooden planks, leather and rope.
