I have tried a few toons to get unconquered status, but lost them eventually either due to lag during fight or sudden burst of spell resist (happened once with my Demo) or just my wrong judgement of the situation. However, I find it a bit disturbing to play unconquered (for example it might be better to complete destiny quest in Tortage and then go for quests in Underhall, Acheron ruins; but I find it lorebreaking to do those quest after Strom is killed). However I am also very much fascinated with Unconquered status. The problem is it is getting boring doing same quests again and again due to rerolling. What actually would I lose or miss if I do not reroll and continue my toon to endgame.
I am a person who loves exploring places, learning lore, and not much into endgame and dislike powerleveling.
