This totem is useful in group PvP to lose aggro of enemy pets. Opponents who switched to another target after sending their pet after you would likely not re-target you.
Pets who have been directly ordered to attack a player will not be affected by Stoneclaw. Therefore, Stoneclaw is rather ineffective against Warlock and Hunter pets (unless the pet has engaged on its own). However, timed correctly, the totem will attract the attention of druid Treants and snakes from a Hunter's Snake Trap who do not have well-established aggro on a target. For example, if a druid uses Force of Nature on a priest, a shaman may drop stoneclaw and the treants will be diverted to the totem. However, if the priest has done anything after the initial summoning (shielding, healing, etc.), it is unlikely that the totem will produce enough aggro to draw the treants away (fade does help). A priest's Shadowfiend is highly resistant to the effects of Stoneclaw.
