Lore will never make sense with an actual RPG plot, because the plot requires the superhuman PC to vastly outshine any sensible limit that could be imposed on a person by the physical rules of the world.
It will, if we all remember that gameplay doesn't strictly = lore. For example, we see Leliana's head get cut off, and she dies... But I doubt there is a "Did you by chance land an execution animation for Leliana?" option in the DA Keep.
Another good example is healing potions, in any game. They are there mostly for balance reasons, because we need to heal from something because no body wants to back track, barely move at camp for weeks while they wait for their wounds to heal.
But it isn't lore-breaking to say that a group of experienced leaders like Cassandra, Bull, Blackwall, etc know how to fight and do it better than others who have probably not even been in an actual fight before. In game, we don't see that reflected, but if it was a book we would be able to see "The Freeman looked to be only 20, and held his sword clumsily. He looked at Cassandra and raised his sword, his face screwed up with fear and adrenaline. Cassandra remembered her first real fight, and took no pleasure in easily cutting down the youth." and know Cassandra has an advantage not because she is important to the plot, but because she has much more experience in fighting.
To relate back to the original topic, I know a book wouldn't describe all the lights going off and magic rings on the ground. Its a gameplay element to show the player that the game is responsive and their ability has gone off and is awesome; Its just over the top. Tone down the lights please, I don't care if that still means temporarily edging blades with purple light I just don't want (as I've said before) every fight to look like a fireworks show.
