Void is not completely useless because defense doesn't matter in typeless damage or if you're in a DPS role where every bit of accuracy/damage you can dish out counts favorably. Ironically, cross-class combat was precisely the thing that players, and in particular F2P, wanted changed before EoC. If you were a mage you had nothing reasonable to wear for melee defense and would get slashed to pieces the moment someone in melee came within range. Legacy was sort of a difficult pickle for them. They begrudgingly made it as an alternative to EoC to emulate the old combat system. Unfortunately, this was already after a couple years of designing everything specifically around EoC to challenge people and force them to take full advantage of those tactics to be successful in quests and other endeavors. For example, Legacy does not have a way, bar a couple weapon specials, to break or prevent a stun/bind/DPS attack. They could retroactively go back and try to make all those boss fights and such doable/compatible with Legacy, but they've said that they do not wish to do so. At least for now... (And don't forget, there have been subsequent tweaks since ~15 months ago, when this was first posted...)
