This was one of the points I was attempting to make with the Hearty Vs Frail discussion, as well. Starting system for the categorization of races who are 'better' at absorbing damage (Albeit in a lopsided manner, when other settings approaches are taken into account) will restrict what players feel they can play. And, on that topic, starting a system will inevitably see more pieces attached to it as time goes on. Hearty/Frail influencing Body via Hearty will move to other system on "That sword's too heavy, buddy" (like the current setup RE: Elf-Races) or "Sorry, you can't figure out how to just be a fighter" (RE: Hoblings) over time, as system-begets-system-use. This would see more people (to go to @James Trotta 's point) of players being punished by system for playing a race they enjoy.And one of the worst things in the whole system, which Mike pointed out, is the impact of race. You want to play a fighter? Choose the right race or have an inferior build. I don't want to feel punished for playing a race I enjoy.
