Good God no. I feel like glow effects are one of the few things in this game that make me think of really crappy F2P MMO's. And WoW. Like that horse with the shimmering hooves... looks so cheap and dumb and uninspired.

"Hey guys I've got this radical weapon design, how can I make it look da coolest?"
"How 'bout you add some glow? Kids are into that these days!"
"Oh gee thanks, 3 seconds of work and bam you've got the awzomest weapon evar!"

(Just imagine the above conversation, but in Japanese).
