I have not played the original tactics, put in tactics advance in a few areas you could lose characters if they died and you did not revive them at the end of the battle...
The tale is of my viera white mage, caught seperated from my group in one of the jagds, she was cornered so no healing and the rest of my team was stuck due to a time mage getting a luck slow, and a defender blocking the exit...
She knocked the thief out as he had only 10 hps left, and managed to get to the time mage and heal herself while stomping him down...then the defender got behind her...R.I.P. Noel you saved my hide.

I was a bit sad, she was one of my original start characters...then I ran into a viera white mage after one battle...named noel?!
and then I just sort of left her behind my defender in training in battles after that.
