Not true. A good Charge Vulcan is definitely worth sphering, especially on an android using D-Parts and Red Ring. The ATP from your armor and shield are also applied to your weapon %s, giving Charge Vulcan an additional 55 ATP in addition to its own ATP when sphered.I've Sphered anything worth using, yes. I'm not going to Sphere Charge Vulcans because it doesn't make sense. (100% would add 37 ATP.)
Since a Charge Vulcan hits 9 times, those ATP do add up.
