Viable 5 man melee setups for PvP

[Gala]

Shapeshifting into ghost wolf doesn't break slow/roots.

When hots don't stack then I guess ferals aren't worth it either. I also don't like that they have such a fast attack speed in cat form. I prefer melee classes that hit slow but hard so there is a chance to one shot the opponent before he is healed.

After all I guess you are right that Warriors would be the best option for melee boxing since they have charge as gap closer.
Maybe 3 warriors, a disc priest and a resto shami. Magic dispell against frost mages, tremor totem against fear and WF totem to enhance the warriors.
The two healers would stay in the back and keep the warriors and each other alive. If the healers are getting focused the warriors could intervene back to them (not sure if intervene is available in classic).
That setup should at least work pretty good when it comes to dungeons and is maybe kinda viable in pvp.
