So I see posts by users talking about how they get horrible rolls and damage and that there is something wrong with the game.
I believe the issue may be that when fighting in the dark, some races like Gith and Humans (Laz, Gale, possibly the protagist) can't see in the dark, so they attack with a disadvantage in dark places. But depending on a users brightness/contrast settings, it may not be obvious that this is happening. While you could put a disadvantage status icon or something on an NPC, it may not be obvious WHY they are at disadvantage. (Is it height? Is it light? Is it a spell effect?, etc...).
Other useful combat banter would also be welcome. "I need healing!", "I can barely see in here!", "I'm blind!", "I can't move!", "My weapon does nothing!", etc... Obviously not when inside a silence bubble. =)
