Wipes are actually good in some ways . I wiped on last boss of a dungeon and thought "Oh no this is too hard " but next attempt was successful and I got a nice warm fuzzy winning feeling .
If its too easy then it becomes boring .

I actually heal better when Ive had a few glasses of wine because then I dont panic as much .

But once you run same dungeon a few times you get more comfortable and the panic doesnt happen as often .
