So this means either 3072 ender pearls or 1856 emerals.
Both are horrendous!
I would not know how to ever get them in these masses without spending weeks or even months of gridinding (and I already built quite some other expensive gregtech items, but this is a whole lot more effort.
Am I missing something (maybe a recipe)?
Don't be a n00b and whine for the highest tier item in the game to be made easier. Just build a fully automated enderman killer, and you'll receive dozens of pearls a second.
All one is is a platform in the end that is located out of chunk loading range of the island. Run high voltage cables in the floor. Due to location, dozens of endermen will spawn there per second, and they die to the extreme voltage you run through the cables. (you can generate the power you need with wind mills)
Collect the pearls on the ground somehow, I think one of the gregtech blocks sucks items up, if not, figure something out.
