I thought it was kind of stupid to have a skeletal pet for most of your life as a necromancer. So my suggestion is that pets are upgraded as you progress through the game, perhaps something like this:
1,4,8 - Skeleton pet
12,16 - Bigger skeleton pet
20, 24 - Zombie pet
29, 34, 39 - Ghoul pet
44+ - Spectre pet
Stats could be the same, but pets would look different.
