Is the 'in game' ability to be able to 'delete' a "multi-class subclass," or classes.
I mean this would expand the 'experimenting' of in game play, albeit it probably should cost some plat and shards and maybe some collectables and/or ingredients... You probably should lose all of the levels of that class. Not to mention other possiblities too.
I have a 15 Bard/1 Sorc... Bad move for my bard! He's almost capped and he's lost a great deal in trying to increase his spell points. I know there are a few guildies too that would love to be able to do this. I'm sure there are a bunch of players that would like this ability, instead of re-rolling their toon. There's a ton of players that don't even bother with the forums and such, mostly because it would detract from their game time.
