Hello there
I was wondering if this is intended or a bug.
Currently while transformed as Ravenous Goliath I'm not gaining any ultimate from light/heavy attacks nor other sources such as Necrotic Potency or Corpse Consumption Passive.
Bone Goliath is a unique ultimate lasting 20 seconds so I can understand if they'd want to curb continuous Bone Goliaths. The only other ultimate I could think of that's comparable to Bone Goliath is Magma Armor which does allow ulti-regen during it's duration. But it also comes in at a 10 second duration vs Bone Goliath's 20 seconds.
What do you think?
