Rallying Cry's damage buff.

Rallying Cry gives allies Added Attack Damage based on the damage of the Main Hand Weapon, however, some (usually) minions don't benefit from that buff, i.g., Phantasms from Summon Phantasms Support, Sentinels from Absolution; any unit that Casts instead of performing Attacks.

I suggest changing the Added Attack Damage buff to an Added Damage buff. This way, the skill will be more consistent as a damage enhancer.
There might, in consequence, be a need for reducing the buff's overall strenght on spells. Adding the line "Buff has 50% less effect on spells" should do it.

Good day.
