Considering that we already can beat legendary quality pets with blue quality pets, I dont see that much of a problem. Plus the aspects is not that great a selection of races. 2x Beasts, 1x Dragonkin and 1x Flying.
Mechapets is already quite common in pvp, like Son of Animus or Clockwork Gnome, so they will brutalize Xuen and Niuzao with extra damage.
Magic pets is also fairly common in pvp, like all the dragons with magic attacks that will mollest flyers while remaining resistant to their damage.
And humanoid pets is having their 'star' in the Anubisath idol whom will crush dragonkin.
Hrm, I just realized one thing. An Enchanted Broom
using ability 1,2,2 will have counter moves to all 3 types of aspects. Though it might have too many points wasted in speed, being only 325 and possibly getting outspeed by the aspects.
