I'm very much enjoying being able to fight the Hallows End wild pet battles in my garrison. There is one spot right next to my managerie which is nice for pet leveling. Fight then heal then fight. No re spawn timer, no heal timer.
I'm using Murkalot and my Darkshore Cub. Murkalot has a shieldstorm that allows me to substitute in 1st level pets for 1 rd and he kills fliers, which are the common second pet. My darkshore cub does well against the critters, and I am sentimentally attached to him. I'm certain there are better strats, but hey it's working.
