It's insanely overpowered. 30/24% damage increase will guarantee to win you every single teamfight you take part in, even if you might be outnumbered. Compare and contrast Vlad's ult - similar application, but has a longer cooldown, far smaller damage amp and smaller AoE.

Also, it's morale, not moral. They are two entirely different concepts.
