I suspect it is way too late to make this feature optional, but also know that if you don't ask, you are unlikely to get
In the latest stream-cast, Amber pointed out how the new text rendering has a background that makes it much easier to read, regardless of the background. I agree that the effect works, and is a clear gameplay improvement. However, the text appears to the *on* *top* *of* our view of the game world, rather than *in* the game world, and that breaks my immersion a little. Depending on how I am playing the game, I might prefer the other effect.
To put it in a bit more context - sometimes I am having fun throwing stuff at the D&D rules, and mostly playing the number/kit game, I am roll-playing. In this mode, the clearer text clearly make for a better game. Other playthroughs are a lot more about the immersion into the characters and the story, I am role-playing. In this mode, I prefer to minimize the chrome around the game, and play with a more immersive interface. This is why it is nice that different UI elements can be toggled today, supporting my own variety of play styles for the same game, and a trend that I see is supported for some of the new features like health-bars too - which is much appreciated!
