Just had a quick look at The End map, and it appears the End Fortresses are in the neighborhood of 5000 blocks apart.
That's a lot of very dangerous exploring for what amounts to nothing in the chests. I mean, wings that do nothing? Dragon bobbleheads that do nothing? Armor we already have? The only thing out there worth the hunt are End Rods, and I whipped up a chest of those by mowing down a purple forrest and killing some Blaze. Purple block can be crafted from purple trees; endstone bricks can be crafted from, well, endstone.
I don't get it.
