Yes, you. You say that Dragon Age 2 is a bad game and i completely agree with that. You also say that the XP mechanic is bad. If you say that the XP mechanic is bad, then you pretty much say that all of the old good rpg's are bad since they all use it.
Bloodlines and Deus Ex are a completely different category of games and are not that much comparable to BG, ID or Fallout. While their mechanic is also good, it doesn't belong to the IE games from 15ish years ago. The whole point Obsidian is trying to make is to stay true to the old good mechanics as much as possible, upgrade them, and add a new world, story, lore, graphics to the mix.
