Voice of the Dragon skill-worth using ?

[Madstrike]

would it be worth going for 2 points in voice of the dragon to boost my royal griffins morale by 2? Im a mage, and currently using them along with pallys, inquisitors/archmages, and 2 archer units(hunters/elves/bowmen). I sometimes change a few units(knights/horsemen/druids stay in the castle in case I need them) but never change royal griffins nor pallys.
Basically Royal griffins are my cannon fodder and damage dealer(or should I say their phantoms xD) and against ranged units I just target my pally. So my question is should I boost their morale +2 in voice of the dragon, Ill have to go up to that skill from glory(which I have not a single point in it but was thinking on spending runes on it instead of voice of the dragon)?
Alternatively, do u guys think its worth spending points into quick draw since I like using 2 archer units? I rly dont see the appeal of getting those +1 defense/attack skills from the warrior skills tree...
