One of the reasons humans tend to get to pull stuff immortals can't is that said immortals are very much bound by their natures... and humans not so much. Immortals, left to their own devices, tend to operate in rather rigid behavior patterns. They are immortal due to perpetual motion an object in motion stays in motion and object at rest stays at rest. To be immortal tends to require them to make a very primal part of themselves permanently fixed. They are contract workers on a salary... Humans on the other hand are very much hired temps.
The very core of a human is flexible as mortals are transient. They come and go. Always in flux. This means they can change things as they are the polar opposite of the unchanging immortals. Mortals are the wet sponge thrown into the clockwork. Often it does rather little... sometime they get caught up in things they have no business being caught up in and snarl up the works. Sometimes they screw things up and the gears rust a bit. Sometimes they wash things already jammed into the gears out.
Basically, mortals tend to cause issues as they are an Out of Context problem. No matter how much you think you (an immortal) have figured them out... some random idiot will do something so inexplicable that it comes out of left and smacks you in the back of the knees... while playing pool in a bar.
The locked nature of immortals is the reason for bizarre weaknesses like being forces to count small objects if they are thrown on the ground in front of them. I've always wanted to see some immortal or another throw a precounted handful of small objects as a trap so they can flee and the human totally ignores it and a dozen other specific weaknesses that don't apply.
