Hi, I have noob question regarding healing as a priest. I recently started lveling my holy priest using LFG. I see, in few topics thats shielding a tank is right thing to do. Few years ago, in tbc i used to have a priest, lvl 40 or smth, and as far as i remember shielding a tank was a no no because tank couldnt take aggro. So has anything changed in meanwhile or I have some kind of false memory?
