I got 100 dungeon part on my MAIN long ago and I still keep actively doing dungeons for AP and other stuff.But on my ALT I prefer more casual playstyle, just some relaxed solo world questing when I am tired of challenging group content - currently being at 21/100 dungeons complete and horrified of necessity to do five times more just for the appearance - and then repeat on 6 other alts. So the change is absolutely welcome.
