Hi!
Today i was questing in Arathi Highlands, doing all the elite quest chains. We got a priest healer in our group (Won't say name). She shielded me before i pulled and i asked her not to the she kept doing it. We eventually got into a fight and she left and ignored me. So because of this i decided to post here to inform you of this.
Druids get rage from being hit. Don't shield a bear before he goes in to attack, or he won't have any rage to maul or swipe to get aggro. Save the shield for an emergency. A HoT before he's in combat helps, though.
GL on healing and don't go around being stubborn, if the tank ask you to something it is probely for a reason.
