Goblinization, How does your GM interpret it? Options

[2Claws]

I was looking through SOTA, where they restated that elves and dwarves change in utero, but trolls and orcs, can goblinize.

One of my other SR GM's, not Seasong, strongly disagreed with that concept and lets all metatypes goblinize. There have been occasions where I have been curious about the potential stories of characters who became something else besides a troll or orc.

What would it be like to have been considered overweight and ugly and then change overnight into a lithe fineboned elf? How would that effect the relationships. In the same vein, how would someone like a pro basketball player adjust to being less than half as tall as he was before?

During one of those conversations, I once brought up the much hated SR novel "Shadowboxer" as a very very rare example of a goblinized dwarf. I wasn't sure if it's inclusion was a mistake on the editor's part or as a canon indicator that in very very rare cases, it could happen.

Have any of your GM's given lattitude around goblinization also, or do they work pretty close to the book?
