My wife and I have 50 WHM and PLD respectively.

When 2.x came out we leved WAR and BRD respectively.
We got them to end game. Went back did all the quests and stuff for out 1.x job but we talked about it and don't want to play few dungeons before playing them in endgame.
Say one around 15 25 35 45 ish just so we know what the hell we are doing on these jobs.
