The color of the DoT flying text need to be in a different color.

Blue text is raw damage by another player. Thunder has an initial hit and than the DOT effect takes place. Only DOTS that doesn't do that is Shadow Flare and the ninja one. Basically any dot that isn't applied on the boss but on the floor.

So like Viridiana said, that the dev team would have to separate each players DoTs fly text before changing it to another color. And I'm guessing coding like that isn't less than 3 lines of code.
