While it doesn't make too much of a difference either way, I would say that the elf and dwarf racial bonuses are the better ones. The only reason I say that is because they are both percentage based, so while qunari and human might have the early advantage, as the game goes on and enemy magic/ranged damage increases, the elf and dwarf bonuses only get better and better.
While I don't know the exact hp scales for DAI, 50 hp doesn't really sound like a lot. Perhaps 5% extra hp would put it more in line with the dwarf/elf bonuses, so that it gets better and better as the game goes on.
But like I said, not really a huge deal, unless there was some sort of competitive MP mode in the game. Then of course people might complain about these little imbalances. But yeah, the main point I was trying to get across is that in a long RPG, I think abilities that scale (elf/dwarf racials) are a lot more powerful than simple base amounts (qunari/human).
