Raven's Mend Flesh vs. other own pets...

Greetings. It’s a take two with this issue, I hope it finally gets attention I think it deserves…

Back when I first started playing GD (about a year ago, to be precise), I went with pet-centered Conjurer, and I noticed that the Raven only starts using Mend Flesh on myself when I’m “sufficiently” low on health, so to speak, and completely ignores other pets’ health until then. At some point, it completely stops casting MF until I get hard-hit again. Is it intended to be this way (trying to evade “passive” playstyle when the player just chills out while his zoo stomps all around into the oblivion) or is it some kind of a glitch? I’m not sure if I should bother picking Mend Flesh in solo play, unless I go coop to heal up my party mates (and I’m not even sure if it’ll work correctly on other players and not like on my other pets… :-/).

Please, enlighten me on that matter.
