Suggestion: Seeing that this is a rules/pnp centric mod, why not go with the correct rules for FR elves/half elves in PnP? FR elves are the same height as humans, and do not require smaller armor etc.
Earlier FR crpg's such as the goldbox games implemented this correctly (not the game engine per se, but the manual describing them as 'tall'), but for some inexplicable reason ALL of Bioware's FR games, (BG, BG2, NWN, NWN2 etc ) have elves in a supposted FR setting game set to Greyhawk elf height and description... why not take this as an opportunity to correct this oversight, as well as reduce the content slightly for this mod since resized equipment for elves/half elves would not be necessary?
