One thing I hate about WAR in that BC is that most of them pull hate and die like retard
Having 2-3 melee in AoE range always end up costing a ton of mp to mage, and turn hate toward them due to massive healer.
I don't know if one is better then the other, but I did it a couple of time with both setup, and it work fine
Concerning the topic's creator party, the only thing I've to say is good luck. If you manage to beat this BC without WHM (and not using lame strategy like smnx6, or blmx6), you deserve a trophy
