If a person makes 20+ wool, it is going to be a hassle to break all of it. Not to mention that they could make a trap with the wool, and use it to make a "dome" around a player and shoot them with arrows through an opening of 1x3 sideways.
There are just too many ways to exploit the addition.

 

Again, not likely, however is very possible. You'd be surprised how much wool I have had.
My personal opinion, this would solve problems, but creat new ones.

 

Why do you think people sit in holes lol?

 

People sit in wholes for the same reason as sitting in their own "fortress of wool". As you said, it is "Survival".

 

Some people sit in them inorder to last longer, because if they have a bow/arrow they could have it ready to shoot anyone who comes near. Some people use these traps to "Survive" which as you say, are what the games are about.

 

I would agree if I have never purposely gone in holes, but I have sooo...

 

I am going to say this again because I think it could work just as well as the wool suggestion minus the issues of placing blocks in important spots, building shelters, ect. What do you guys think?

 

If you could break wool then you could grief certain buildings in some maps.

My point is, if the blocks are breakable, then they serve as nothing else than maybe concealment (but that's not possible, because it would have to be a block the map doesn't already use so you can break it)
And if it's unbreakable, refer to my previous statement.

 

I for one feel that we should be able to find leaves in chests, and have the ability to place them. We can already break leave, so it's not like that would be anything new.

 

We had this already with melons, it created too many problems.

 

I would build a tower xD. But that would give kit users a advantage. +1

 

+1 on this too (did not see it b4 other on)

 

I like the ides but another suggestion along with this is to just make all holes insta-kill....lava traps.
