Gravebind rope cuffs + Banner skills

Situation:
Currently playing with a Titan friend so he most definitely is using attack skills. Stampede, Earthshatter and Hammer of the gods to be precise.

I'm using Gravebind rope cuffs + Alpha's howl and even a low tier roll of presence AoE on scepter to actually have a full screen worth of presence.

Bug or problem:
I'm not accumulating any valour for my banner skills from mob kills.

same here man really sad, it make useless the banner.
