The pets designs look good, but the legendary one should get a buffed hb, I think it's time to have legendary stuff to actually be useful.
HB: +30 primary stats, + 20 str dex int, 15%dmg stack, 20%ms stack, +500hp would be decent
.
As for the aa, a little buff would use a buff (in case the range and rates of terrorize and banish are too low) , maybe weakening enemies with a 15% dmg reduction or a 10-20% armor debuff (5-15% in pvp)
