Guys lets watch how we are phrasing replies so they do not come across in unintended ways.

To address a few points made:

  • Tranportation Portals: The wide use of the transportation portals is a concession to computer gaming and the fact that a HUGE number of players will hate on a game without fast travel options. While the portals like this is not "lore", it is a normal and often expected CRPG game mechanic.
  • Throwing Potions: This one is a stretch for sure. I think the most likely answer is that this was a game mechanic Larian had used before and they thought it was cool. Personally I agree it is out of place and even it was viable I hate the implementation. If the throwing potion works then you should only get the MINIMAL effect possible from the potion as a huge part of it is wasted. However I agree this just should not exist.
