For most actions made by a player or creature you can see them in coloured lines. When something hits you, you see it in red, when they miss, it's green. (don't like the purple lines ). During combats you see a lot of lines coming by, and i'm not talking about the please wait x more secs.
During all those actions some events are also non-coloured, like breaking your weapon, or even worse the breath of an creature. Sometimes you don't notice them and this could lead to bad situations, like the purple lines. I'm suggesting that all events should have a colour, red green or another colour.
