I would like to share an experience of me.
I'm having some difficulties choosing the best setup in dungeons, especially heroics, with keeping my pet's alive. First of all they always get forgotten so they hardly receive any heals or buffs.
Last time I was in heroic with my bear which has Tenacity talents which are pretty good for tanking i might add.. and i've set them on tanking combined with my own survival build. My gear is full epic so I have about 24000 hp unbuffed and my pet benefits from my stamina and has got about 20000 hp.. this is pretty good or at least enough I think so.
Then (like many times before) I had buffs but my pet didn't have any buffs the whole time. pet's get forgotten so many times..
But anyway my bear died 3 times in a row in this single heroic.. then when i asked for some heals and buffs for my pet I received a big mouth into my face from the healer and others from the party... so i just left them as angry as I was...
Then the next day i was doing heroic again with my bear and i got a big mouth from the healer claiming he knows a lot about hunters.. he asked me why the hell i was using a tank pet.. he told me i should get a dps pet. So i told him no,.. i need a tank pet because otherwise it would die way too often. and i am not a beast master.. I am survival build anyway so i don't really need my pet to do dps.. I get most of my dps from my ranged attacks... the difference in dps and tank pets isn't very much anyway.
But the next thing that happened we wiped in the pit of saron on tyrannes, last boss.. Then the healer quickly started to blame me and that my pet pulled a different group of mobs accidentally... while in fact the healer was standing too close to the other group of mobs himself and pulled them. it really wasn't my pet.!! he was on tryannes the whole time together with our tank.
I'm sure many of you also experienced this kinda sad situation before.
And I think blizzard should do something about this.. personally i think the amount of talents pets have really isn't enough... if we don't have the extra 4+ talents from BM we can't even get to choose the last pet-talents 2x "Wild Hunt". we get it only 1x.
Personally I think blizzard should add at least 2 more talent points for non-BM and BM hunters.
We as hunter claim to be master of animals but in fact while our pets can't really do that much good at all. Most of em are good just for their looks or handy ability. this is just my experience so far.
But hopefully I'll get some better ones soon

I also have a beast master build with spirit beasts loque'nahak and Arcturis but my experience is that i do more damage with my survival build in heroics. And many hunters surely must agree with me on this. I also love BM more!! but it's just that survival hunters do more damage since WotlK came out. Or maybe do i see this wrong?
Maybe someone else has a good idea about a better pet/talent setup? or a plan to confront blizzard about this problem.. haha?
