I believe you may have misread what I typed, as I was referring solely to my own experiences. I almost exclusively play Cata FoW where there are stacks of elites. It may be that I don’t see this occur very often because I usually play Foot Knight in teams with low stagger comps (DD/Longbow Shade, BH, etc).
I agree it’s a problem and it needs to be fixed. Foot Knight’s charge should override any other stagger in the game and not be overwridden by any.
