I use Sphynx as test mob and time fights. Besides Consume Damage, there are no other buffs on the pet. All my Cus have 700 Str, 150 Dex and maxed regen (hp, stam, mp).
During the first 3-4 fights, the AI Cu comes out ahead but loses that advantage over the next fights. With almost instant Sphynx respawn, there's not much time out of combat, so I guess it's a combination of AI costing tons of mana and bandages having priority over AI. When I run tests with Discordance on my Tamer, the AI Cu stays ahead.
I have a Disco Cu now and that one really lays down the law. It's not yet barding difficulty 160 mob ready, but Sphynx works from time to time.
Disco costs next to no mana and doesn't reset the swing timer. I switched to the two Peace masteries with this pet and will likely switch out music/X for archery/tactics, one the pet is at 120 Disco.
