Alternative skill color themes for classes like Guardian, Necromancer, Mesmer, possibly even elementalist would be very popular if implemented. Some classes obviously don’t have such flashy ‘magic effects’ to their skills and wouldn’t benefit from something like this.
To clarify, what I mean by this is the ability to change the color of a character’s skill effects. For example, a mesmer’s skills purple/pink color scheme to green. Or a guardian’s blue light and fire to red instead.
Anet could easily ask for 800-1600 gems for this and people would want it.
