Well, technically that's Stormcaller because it's continuously firing. And a Sunsinger can use a gun that fires faster while they're in their super (not saying they should, just that they can). But I get what you're saying, and I do fine with the short duration as it normally is, but a reduction to an already very short super seems unnecessary and overkill. Doesn't really bother me because I'm too on love with Tripmines to ditch the Spine, but those complaining have a valid argument IMO.
