So I'm in the early game of AllTheMods10, and recently Ive been getting into AE2 which requires ender pearls for some of the more advanced crafting stuff. I was having a hard time getting enderman to spawn so I decided to make a enderman gateway pearl. I was super under geared and probably would have died. That is until it started raining. The enderman cant run away since they cant leave a radius of the gateway and I was able to complete all 4 waves without even drawing my sword. This netted me about 128 pearls per gateway. Since you can open multiple gateways at a time you can get thousands of pearls in about 5 minutes.
