I voted for Death.
In order of preference to have at 3+:
1) Death
2) Air
3) Fire
4) Earth
5) Astral
6) Nature, Water
8) Blood
In order of preference to have at-least-1:
1) Astral
2) Water
3) Death
4) Blood
6) Earth, Air
8) Fire, Nature
So I guess my least-favorite path is nature
. Mainly because it's available on so many independents. If it weren't, 1N would be quite important.
