At the moment the pet breakdown looks like this - for Tier 8 pets:
Magician (Fire, Water, Air, Earth)
- Of these pets, the only one worth using is the Air Pet (Monk)
Necromancer (Skeleton, Zombie, Spectre, Vampire)
- Of these pets, the only one worth using is the Vampire (Monk) or "Hooded White Guy" as Melkor likes to call him.
There have been numerous occasions where I've cast the pet spell over 20 times and still didn't summon the desired pet. This can be especially tedious for the Necromancer since the pet summon spell is a 16 second cast.
I know this likely plays into a larger issue; however it would be great if the summons were cyclic. What I mean by this is that it would cycle through the different pet types so that at most, it would be 4 casts before you got the pet you wanted. Really though, and I likely speak for pretty much everyone who has a pet class character. Other than the monk pets, the rest are practically never used.
