Woo hoo! We finally get to hear the big guys talk about the most interesting magic system!

I will say, I hadn't considered the possibility of the Donor's Bindpoint effecting the spike's Identity before.

Edit: just finished listening to the podcast (it was really good, thanks guys ) and there were a couple questions you had that I found WoBs to answer:

1. Hemalurgic donors are actually worse off than Drabs (WoB). Perhaps this has to do with the process of ripping off their latent Investiture than the amount taken compared to a Nalthian Breath, but regardless, it doesn't leave them in good condition at all.

2. Steel Inquisitors don't all age more quickly than normal (WoB). Some do, but some live longer depending on the specific power set they receive.

I also thought the idea of Identity decaying off of pre Catacendre spikes to allow for Compounding to be quite interesting.

My personal hypothesis for it as of right now is that since Ruin was actively pushing into the Spritwebs of people in any way he could, that made more pathways in the Spiritwebs of Hemalurgists to mix and meld together, which consequently allowed for Compounding. However, when Ruin became subservient to Preservation, those pressures from Ruin's Investiture stopped, meaning that the spikes lost those extra avenues in the soul and became more separated from the rest of the Hemalurgist's Spritweb, so Identity contamination would become an issue.

I hope you really cool guys find this at least a little useful 

I LOVE IT!

Marsh is one of my favorite characters in the Cosmere, as it happens.

My guess as to who these "off worlders" are? Rosharans.
