- "your xp will result in ridiculously fast leveling for this system" - Correct. That is by design. I am not in favor of skipping the first couple of levels, but I am also not in favor of having the characters stuck at level 1-3 for any longer than absolutely necessary. So I am handing out enough xp to get them to higher levels pretty quickly. I want them to advance quickly.
- "the +100 per hit die is especially out of scale with normal monster encounters..." - You hit a nail there. I wasn't thinking when I did this. Mechanically, there would be no difference between hunting nine orcs and encountering a 9HD dragon. Except that surviving the orcs would be much easier. I don't like the table on page 32, because I think that the progression is too slow for my tastes. Also, I don't like referencing tables. Lotfp has nicely done away with most of the tables during actual game play.
- "for treasure to count for xp - it has to be returned safely to civilization" - I don't want the game to depend upon collecting treasure. I don't want to hinder mechanical character growth. I want the characters to advance.
(HD x HD) x20
That would give an orc a value of 20 xp, a gnoll a value of 80 xp, and the 9HD dragon a value of 1.620 xp (or rather 2.000 xp, because due it's breath weapon and other abilities, it counts as a 10 HD monster).
Now hunting nine orcs will net the group 180 xp, and hunting nine gnolls will net 720 xp. Still considerably less than defeating one dragon.
