And, the RNG is notoriously flaky when it comes to pulling elementals with the GPA anyway.
Going for just ore, I've had GPAs give 1, and another give 8, on the same trip.
One time about a decade ago, my guild was between Spirituality and Sacrifice in Ilshenar, deliberately trying to bring up paragon ore elementals. I didn't get a para that trip (though as a group we spent about 10 minutes fighting a paragon valorite - made more complicated when it chased a party member into Meertown and the Eternal got involved, killing anyone that got on the screen with it and the elemental). However, while using a UOA macro set up to do 10 swings at a spot, I got FIVE Shadow iron elementals in the last 9 swings - and killed them all autodefending with an elemental slayer (my miner is a legendary macer, and had EoO cast before digging). in fact, the first one dropped right as the 3rd one spawned, and only 3 were standing when the dig macro ended.
