(4). Demi-human level limits?
I'm in favor of them. A flat Level 8 limit for any non-human of any class except Thief and its variants. Short races reduce max level as a Fighter proportional to height. Honestly, why do people object to this? If unlimited level advancement is important to you, don't pick a demi-human class that has a level limit. If being an elf or dwarf is more important to you, do that instead, and deal with the level limits.
But... Just because dwarves are normally limited to 6th level as a Fighter doesn't mean that a player can't find a way to push beyond that limit. Instead of bitching about the rules, make that your character's quest: "I want to be a respected dwarven lord and start a barony, exactly like a human lord." OK, find a way.
