This may be thread-necromancy, however this is the most relevant existing thread I can find on the topic.
Is there a particular reason for the increasing body reductions for all Elf-types? Outside of giving a double-benefit to the races who get an increase (the second benefit being not getting a decrease), this has a high potential to chase players away from playing (arguably) one of the most traditional set of races that belong in a high-fantasy setting.
Is the intention to "water down" high level play by a requirement of Hearty to survive certain encounters, or to purchase death/damage avoidance abilities that attempt to illustrate the "elven litheness" that's pictured in nearly every representation of their existence in other fantasy settings?
Either route seems punitive rather than enriching, as it creates a build-requirement for a 'base system' created problem.
