uSpez is pedophile , and loves his rpedofriends ! <| sep |> But with the Ferryman you basically always have the choice to bring back something or not , except if you have like 2 mana in which case you rarely want to bring something back <| sep |> It ' s situational . If you have another tank next to you , then you most likely want to be shooting at stuff . If you ' re the only tank around then you might serve your team better by shielding them , especially your supports . Definitely put matrix up when Pharah , Soldier , Roadhog , Bastion or Reaper pop their ults . Using matrix while boosting towards enemies particularly turrets is useful , but don ' t waste it if they ' re not firing . You can also support Rein , by putting DM up when he has to lower his shield . There are loads of guides out there with much more comprehensive information than this , so go take a look .
