I'm still thinking of other mixes (like paladin or Dragonslayers fear wards), however thus far I think the above has the best utility to them. You can in essence get Req in there, but not epic inspiration :/. Still, figured id post it here if anyone had any ideas as to how to make a proper build, and what type of attack one should focus on (str-based bard? or charisma for spells/auras etc.) One can add EDM for power, however if going with my suggestion above, effective CL is at 27... which i think is 1 short of "dispell safety".
Input and ideas is therefore welcome
