Glowing effects on "upgraded" gear.

[Gramul]

I have no more solid information on this point than anyone else in the thread, but my guess would be that the majority like it briefly the first time they get something with a special glow, because at that point (compared to what they'd previously been using) it would still seem special. But that "specialness" would wear off fast as they start doing more content where everyone has the upgraded glowing weapons. It wouldn't take long before the glow becomes either annoying or irrelevant, depending on the player's preferences. So, there's perhaps a brief period where the majority may be happy with it followed by a much longer period where the majority are annoyed by it (or at the least the majority of those who care one way or the other). Seems enough to justify some good alternatives.

sort of like diminishing returns. What at first seems potent looses its intensity the more they come accustomed to it.
One of many reasons I don't care for glows and spikes in the first place. You gotta keep pushing it more and more to make it look more impressive till in the end you have this totally ridiculous piece of nonsense that looks like it came from a young teens deviantart page. Especially prominent with a game with linear gear progression.
I feel the KISS principle is important in all design. I find good gear design is subtle, clear, and iconic.
When you have a new, even more powerful weapon upgrade, try bringing out more of the original designs beauty. Stuff like a good polish, more vivid color, or a subtle evolution in its overall design. You know, don't go overboard.
