There have been some requests to make it easier to see when a character is losing HP (in frenetic battles like Hamlet Defense). While we cannot address it in the current version, as shown in the 2.0 UI image, we are planning to add different colors to the HP bar beneath the name to make it easier to see falling HP.
Also we are planning to make PT members’ HP bars blue and enemy HP bars either yellow or red depending on the claim status.
