His proposed solution is to give a set amount of HP per level (full HP at first, half of your hit-die rounded up thereafter, plus CON modifier). While this certainly solves the problem, I think some customization would be nice. My idea would be to let the characters spend skill points for HP. Some possible variations (not necessarily exclusive):
- Use a fixed "base amount" per level, or keep the random roll and use that as the base amount?
- Allow players to buy more than their HD per level (I'm inclined to say no because of game balance issues)?
- Use different conversion rates for different classes? For example, fighter-types get an even trade, where wizards might need to spend 2 or 3 skill points per hit point.
Any thoughts on this?
