@Bellyon Oh I fully agree! Multiple interpretations are great! I am obsessive with Star Wars species and while I don't always agree with how FFG stats them out, I still enjoy seeing them. I love when I'm surprised by an ability that I would have never thought of. Balance is very important though.
I have an opinion that elves of LOTR are like Jedi in Star Wars. No one will ever be able to perfectly stat them out where we all agree because realistically they are just unbalanced and that's kind of their point. They are the myths and legends of their worlds. However if enough people posted their thoughts, each individual could collaboratively pick and choose what works for their games. I do apologize, rereading my post I do seem to be discrediting your build. Your builds are very good at breaking them down to the 3 for a 1 Genesys racial stats that should be the norm and would be far more balanced at a table. I am very curious how unbalanced it would be to push the elves a little farther since Genesys is such a narrative system. Which is why I enjoy the idea of a race better then the rest of the races while still being a playable race at the table. It's an interesting roleplaying conundrum.
Another idea I was kicking around is raising their starting skill cap a little higher then the other races to represent their immortality. Like to a three at the start of play. This could represent how the average elf seems better at things then all other races but in play over time this benefit would go away. The only thing is Munchkins could take advantage of this and break the game potentially by finding a few ways to get something like ranged light as skill a few times or something else crazy. But again not sure how damaging something like this would be. Probably too damaging.
I love the ideas though!
