inconsequent rampage functionality - some things snapshot others wont

im playing a rampage titan, and there are some interactions that are very inconsistent even regarding the same mechanics.
one of then is aftershock:
Ancestral Empowerment reads "Every second Slam Skill you use yourself is Ancestrally Boosted"
How rampage acts with it is, every second "step" you take triggers an Ancestrally boosted Attack

Mountain Splitter reads "Every Third Slam that doenst create Fissures which you use yourself causes 3 additional Aftershocks ahead and to each side of the initial Area" - so one would think that it behaves the same as Ancestral Empowerment (every third "Step" would trigger Mountain Splitter).
But that is not the case. In this case, Mountain Splitter is actually Snapshotting, so if after you use 2 Slams you start to use Rampage, every Rampage Step will trigger Mountain Splitter, even if the wording is basically the same.


Whats also Snapshotting are "default Aftershocks" so aftershocks from Skilltree + Aftershock Support Gem. If your first Rampage step is triggering aftershock, every step in that channeling sequence will trigger aftershock, basically doubling the dps for the whole channeling sequence (actually even more with bonus from skilltree etc.)

Warcries like Ferocious Roar are Snapshotting aswell, treating 1 rampage sequence as 1 attack

Now damage Buffs wont Snapshot - Rage/Walking Calamity/Slows - so i think the non Snapshotting is how the Skill actually should work?

so as you can see, there are some inconsistencies regarding this skill, and i guess there are even more of them which i may just not have found yet.
