I think it would be better if they changed the TT icon for an NPC to a different style after winning. Right now, the TT icon is totally removed after you win a card. For example, they could change it to blue or green when you beat the NPC instead of totally removing the icon on the map. What if I only won one of the cards and I forgot where the NPC is located(I know the zone, not the pos)? Yeah I could look it up online, but it would save me time to see it on the map.

yellow > unbeaten
blue > 1 card won (yes I know not all NPCs have two cards to give)
green > all cards won

At least this way they still show up on the map. Thoughts?
