Scattershot Support undocumented Changes

The scattershot support gem now works fundamentally different from how it used to before the dawn of the Hunt launch when used with plasmablast on the crossbow. Previously, it function like a burst fire firing three individual single blasts. Now it fires three projectiles all at once. The only thing in the patch notes concerning it was that it now made the skill do less damage, but it doesn't mention anything about fundamentally changing how it works on a skill like this. Either this is a mistake and needs to be fixed or you guys need to document the changes to skill gems properly. If I knew it was gonna work like this, I wouldn't of spent all this time building towards this skill cause now it's basically useless.
