Shining Equiptment can be great in the right kind of Environment.
For example, take Dragon Age Origins. Dragon Age Origins is Dark Fantasy, its brutal, the whole world is gloomy, the whole world has suffered a lot from a war... And now imagine a guy who is shining blue/green/red from each part of his armor. It would just not feel right.
And now look at World of Warcraft. Its got comic graphic, mighty enchants, and the right universe. A guy whos got fireballs on his Shoulders and a blue glowing weapon doesnt seem out of the ordinary.
I personally rather think Divinity 2 fits more in category 1.
Shining equiptment wouldnt seem right in my eyes.
