Well, Gate of Many Worlds did not exist back then and Cataclysm was the go to on pretty much all pet builds due to it having +1 to all skills.
3 Piece Beastcaller was also a lot stronger back then than the options you listed.
Dots also didnt really achieve much due to low %damage and lack of number of pets to apply them.
Like I said, half a decade old post 
Once I got to this - The Fat Fwuffy - Classless Pet Build, I kind of got lazier and stopped making/updating pet builds that were not Conjurer/Ritualist/Cabalist.
