What difference does it really make though? Volcanicus at no point even threatens a single universe nor does Hun-Grr who was consuming Angolmois Energy in the manga as well. Same source of power=/=you scale to the entirety of something, we've been over this with the Matrix in the pastIt dosen't vary. It has the same power source. The Angolmois Energy is the power of the Matrix and Unicron's Angolmois Energy is a counteract to it. It does depend on who actually can utilize Angolmois Energy better. Volcanicus honestly can utilize Angolmois better than Star Convoy since Star Convoy needs to upgrade himself with Angolmois Energy to fight dudes stronger than him
heck Cloud stories don't inherently say "this guy is fighting Cloud Megatron blah blah blah", the narrative states that Angolmois Energy itself can affect Cloud decepticons
Actually you seem to more or less agree with what I'm saying here anyways. If the power/tiering/output/etc is determined by how well they can use Angolmois, then just having access to Angolmois wouldn't be enough of a reason to provide a character with a specific tiering/scaling.It does depend on who actually can utilize Angolmois Energy better.
