I was reading Lume the Mad’s broad summary of changes in WotLK when came across a reference to the draenei spell symbol of hope. OK, shop so I must be a complete idiot but I’ve not cast this spell even once in my entire career! What’s more it looks like it’s a free 900 mana to everyone in the party! WHAT! I’m going to look into this one tonight! Though it’s being replaced with hymn of hope a channeled spell, apparently returning less mana, even so! How come I’ve never come across this!
Interweb you have let me down! [Edit] Or perhaps more specifically, my brain has let me down, Symbol of Hope is a Draenei Priest spell.
