You did not read what I said carefully. I said it would be extremely gimp or extremely op, there is no way to balance that to be a middle ground. Pup would either be over wanted, or not wanted at all (Given way we currently heal, that strongly suggests, in order to make it any kind of meaning of useful, you are running pup with 2 other DPS and tank, same with making it be tank mode, it would be 3 dps and a healer.) Look at the titan failure we have.. it can't take any hit while in low DFs you can make it tank, then again you can run 4 dps in low dfs so its whatever I suppose.
Again there is a reason RDM does not heal in this game and you think giving 2 different healing pets would bring balance? I would just advice focusing on one role, if you want your suggestions be taken more seriously by the dev team. (I would suggest making it DPS only)
You do not need to "spam" heals in this game:
