The simple visual combat log addon that displays skill/spell icons, and includes detailed mouseover statistics. This addon has been around since Vanilla and TBC, and now it's available for Classic WoW 1.13.2.
First of all I'd just like to mention that I am not the original creator of this addon, and for that you can thank Grayhoof (original author), and domzae for his 8.0.1 fix. This wasn't just a simple TOC edit, so if you have any problems feel free to submit any issues.
