All instances that the character run a second time or more, he do it in his memory. Lore wise every instance is only running once.
The character remember how he cleared that one dungeon, back in time where he had lower gear.

So our character has a really bad memory considering each time we do the same dungeon, clear time is different, party members are different, and other different things. O_o
