I'm not sure it's devour itself taking center stage, as these troops only devour a certain type of troop. Two of which (Goblins and Dragons) are general banes to people at various levels. So these are more just very niche counters, unlike something like Kerberos or Kraken who can devour any kind of troop.
We'll have to see what this change entails as I feel it will affect how we perceive these counter troops.
Also @Sirrian minor typo in the OP
Should be branches I'm guessing.
