Titans are more situational in PVP. You just need to know when's the right time to use FoH and the bubble. For example. I play control if I'm actually doing PVP. On Firebase Delphi, I almost always throw blessings of light in one of the doorways where the B cap is. It creates a stalemate between both teams and allows my teammates to go through with every shields and do their best to mow them down. It just sucks that pretty much anything can destroy the bubble with ease.
