So, for reasons which are not in themselves defensible, I ended up eating an int tome on my L7 THF warchanter. This has left me with an "extra" skill point going forward. After covering Balance, Concentration, Haggle, Jump, Perform, and UMD to max, I'll have enough points left to either max or nearly max one more skill. I've got the requisite one point in tumble already, but I've got no idea how useful Diplomacy is. Is there anything else or something cross-class I should be thinking about (the build does sport two fighter levels, if that matters at all)?
