in 2.1, BRD dps will be silghtly decrease. therefore, it not really good idea to run 2 WAR since they do not have silent and you will be require to have 2 BRD for silent rotation or have your SCH do the silent if they brave enough ;P. (If your party have member that have multiple class then you can ignore this ;P)
My guess would be PLD/War will be the optimize tanking combo, since they play off each other well and you only have to bring 1 BRD for silent.
