My hunters now have much better gear, stronger relics and decent advancement in the AP traits. Also with the introduction of the cheap 1 minute potion of prolonged power, it's time to see what x5 hunters can do.

I'm going to use 1 Tenacity Turtle (TT). The rest will be Ferocity. I will always use 1 nether ray for the heroism, and 1 Ferocity turtle (FT) as secondary tank. The remaining 2 pets will be a mix of cranes and turtles, depending on how hard the boss hits and cycles through the pets. Turtles have the turtle shell, even if they are ferocity which is very useful. Cranes are nice with battle ress, either in a fight, or just out of combat when you cant be bothered running in again. I only have 1 engineer with cables and miss guild ress a lot. All 5 hunters can have cranes, and just summon them for the ress when needed, and dismiss after.

I will be using 4 MD on TT, and 1 MD on FT (I may tweak this and split it to 3 turtles instead). When TT dies FT can last a while with shell cooldown, allowing ress of TT and hopefully some time for new threat generation/MD on TT. If a few ferocity pets die before TT gets aggro, it's easy to just ress them again. As BM it feels like without any MD, the pet will still get aggro before the hunter most of the time, so keeping the hunters from being targeted does not seem to be an issue even if a boss cycles pet tanks at a quick rate.

I'm going to switch between the heirloom tank (shield trinket) and pure dps trinket depending on what I feel will help most at each specific boss encounter. My alchemist will be creating a lot of healing pots. I've decided to not bother with spirit beast pets healing, because it felt so low anyway and not worth the trouble.

By no means will 5 hunters ever compete with 5 tanks, and some encounters will be just impossible to survive. But I know fights that should be doable. It would be cool to find one or a few dungeons which can be completed in mythic, and +1 just for getting the weekly chest. Most bosses would most likely require heroism to kill. Also the lack of a healer makes the group very vulnerable to wipes/deaths and requires perfect execution all the time. So beating anything within a timer may be some ultimate challenge for the future. But for the weekly chest we are not required to beat the timer right?

I kind of miss the excitement of x5dps, where the challenges and perspective on fights/mechanics are totally different than from a x5 tank setup which is much slower and more forgiving.
Is there anyone who have gotten serious with 5 hunters (or other 5 dps setups) in heroic or even mythics and have some experience or tips to share?
