Val is still a garbage medic. It feels like her Sniper Rifle and Medgun should be thrown to a Support and have her removed entirely.
Caira laughs at Val with her 30k+ heals and survivability.
Vals utility does not make up for the lost heals.
Val is squishy, has terrible heals and does not make up anything to justify picking her (or Lazarus even) over Caira.
Caira is the god with her irritating personality, boring kit and overwhelming presence.
Val is the janitor who goes around mopping Cairas floors.
Lazarus is the old man who lives in some cave thinking about the good old days.
tl;dr: Val still needs more work done to her.
