I managed to get a 31 win steak till i meet a team with a frogs.
With this team:
My usual tactic is to start with kovok and use pheromones and then switch to the valknije and tank the enemy pets. Once they use the very anoying skill (those that hit for 400-800 damage) i just use haunt and the cc misses. Then i switch back on Kovok and do the pheromones. After that i use poision and a hardhiting attack then i switch to elemental pet and aoe the rest.
But if the enemy has a mehanical in his team, i start with elemental and aoe. (huge attack does pretty nice damage to backline pets) One usual mistake when enemy thinks....oh this pet does no elemental damage i will just keep attacking...and then it gets hit by Rupture Also a good thing abauth elemental pet is that they can soak the mines damage.
Share yours (you can see your team on armory if you are not loged into wow right now-- just print screen and paste it into paint)
