This is not a big suggestion, but it will make the overall gameplay experience more enjoyable for me and probably a few other players.
As of now, I only see 2 options for FlyText, ON or OFF. There is not an option to edit the opacity or size of the text. As I scroll back for a larger scale view, the flytext remains the same size impairing my sight and enjoyment of the overall combat. When you cast an AoE skill, and see nothing but huge numbers. And if anyone tells me to turn it off, i advise them to try when they face a boss or opponent with durations of invulnerability. Waste your toon's resources why don't you..
Aside from that I also hate the current AoE rings that appear under my attack, I'd like to see that optional too..
