Yes the thinking of "you cant take this or that job into Coil"( for example) does need to go away. But WHY penalize people if their group just HAPPENED to have a set up that they preferred to play two jobs together? My group is PLD, PLD, BRD, BRD, BLM, DRG, WHM, & SCH. We all CHOSE to play this set up b/c we had the jobs already geared and if not, GEARED them for COIL b/c it works for us to get through it. Now we get penalized for forming a party that WORKS??? We now have to consider either taking time away from even doing it to re-gear/re-level, or kicking long time friends since 1.0 from our static. I just think its stupid. I like the OP's suggestion.

My suggestion - Instead of penalizing teams with duplicate characters, give a buff to unique team formations instead. The players should be given the liberty to decide what characters they wish to play.
