Just a quick idea I just had:

If Mythic doesn’t know how to make a viable engine upgrade in the future that is possible without requiring a major reprogramming and too much work for the artists, I suggest to put dynamic light effects on the spells. Right now DAoC’s light system is wonderful but it’s also static. It would be great to see a fireball lighten a room and the characters nearby and have all the different spells their own lights and colors affecting the environment.

In the dungeons and in the RvR at night it would look nothing short of spectacular.
