New 5 man 4x Hunters with Priest questions

So I have my original lock, 3x mage, priest group up and decided to try something different and went with 4x hunters and a priest. My question is what the Hell am I doing wrong. Seem to have nothing but issues with the pets in Deadmines. Am i just silly trying to level this group in dungeons like I did with my original and should I instead be sticking to quests in outdoor zones?

The hunters are all level 19 but once I get to the furnace/forge room my pets just seem to wind up getting me zerged every time. I am sure if they could talk they would be yelling LEERRRRROOOOOYYYYY!

I can't really help you with your problem (I don't play alliance and have no clue about deadmines), but I want to level a similar team 4x hunter and 1x shaman.

I don't plan to do instances in lower levels. I will stick with Barrens quests and grinding mobs.

For instances I recommend at least to get 2 owls with screech for aoe tanking and for bosses a turtle with shield. I dont know the exact level for the pet spells.

I think with level 30+ instances will get easier.
