Cancelling Channeling Buffs

[elijiahrave]

So I had this RRT(recent random thought) that begs to be satisfied asap.

First off, let’s recall two facts:

1. Buff count is limited
2. any addition beyond the limit would replace an existing buff (not quite sure with this one though)

Now my question is this, are channeling buffs (e.g. Iron Skin, Melstis, Golden Bell Shield, etc.) bound by the same rules?
Are they cancel-able in this manner?

i believe those are not considered buffs and are not part of the count

I would have thought likewise, but my hesitation sprung from this

Thanks anyway
