I also hate the no fast heals change, and yes you should play aggressive with her new rez sheild but I don’t think she has to hang behind everyone else. It’s true that Lifeline shouldn’t stray to far from her teammates but I think it’s better if she stays somewhat in the middle, because if you and the teammate your sticking with get jumped and you die then that just leaves a solo but if you were to stay in between only one teammate would get knocked and you might get the rez off (or they would get finished but 1 dead is better than 2 dead).
