I generally agree with the tenor of your post, except for this. It doesn't matter how a player is acquired, what matters is how they play and what they bring. Elie was doing very well, I thought, and the only thing Larsson brings is face-offs.
This move really does shine a light on HCPH, again, which, it looked like we were happy to accept the past two games. Put simply, if it's working, don't mess with it, yet, here we are pulling line changes a la Disco Dan.
