Those are all meme builds using 0 Pet based Masteries. Perhaps I am setting my standards too high, but I would expect a proper Hybrid Pet build to outperform atleast those, balance wise.
Though, personally in regards to this particular issue, it is more that I am a little bit sore still due to trying to go for a Hellhound + Rifle build way back before AoM and struggling to even complete the Campaign > proceeding to uninstall the game and only getting back into it because someone gifted me AoM for free.
