If i skip the stealth part and do a :
1 prot war (Undead)
2 fury war (Undead)
1 hybrid dps/tank druid (Tauren)
1 resto shaman (Orc)

What do you think ? Viable enought for both 5man and wpvp ?

For the talent, i really dont know what to use :

For the resto shaman :

No idea if it's viable, i focus on 5man and wpvp content. Since i have a druid, i don't really fear about oom, so i'm more focus to get survivability and efficient direct heal.

The druid :
I guess, probably something like that : https://www.warcrafttavern.com/talen...xw8QATwN_zdATA
Mostly dps, can switch on bear if needed.

Really no idea about warrior, i need to search a little more about them.

For the good and bad :
-Seems decent in term of damage, i know druids dps are meh, but they get they bis weapon outside raid.
-Decent protection against fearbomb, 3 undead have will of forsaken, they warrior ability and i have a tremor totem. But not perfect thought and i will probably need to spec both Tauren druid & Orc shaman as blacksmith to get the anti-fear tricket.
-On wpvp, i can close gap with round robin charge with both war & druids, i have plenty of spell interupt option
-I think it's not a too bad buff synergie, totem to buff melee, druids buffs, inevervate to replenish mana from healer, worst case, i can probably switch the druid to heal in case of oom, one battle rez ...
