Scattershot Support Gem Inconsistency

Scattershot: Supports Projectile skills, making them fire extra Projectiles. Also lowers Attack and Cast speed, as well as lessening their damage.

When combined with certain skills such as Fragmentation Rounds, or Incendiary shot this gem seems to do nothing at all.

When combined with the basic Crossbow Shot, it works as expected, but consumes 3 shots with every use.

When combined with Armour Piercing Rounds, it also seems to work as expected, however it only consumes 1 shot per use, whilst still shooting bursts of 3.

Also, when combining the basic crossbow shot and scattershot, you can run at full speed while shooting if you tap to shoot, without holding the mouse button down continually. (I hate to admit it, but it seems too powerful)

Shockburst rounds also only consume 1 charge versus the basic attack consuming the amount fired (3). And if would have a choice, I would probably choose consuming 1 charge to fire 3. Instead of what is happening to the basic arrow haha

It doesn't even work as expected with most of the crossbow skills. The tooltip for projectiles says that multiple projectiles won't hit the same target if they're fired at the same time, and your stat sheets update as though that were true, but they absolutely will all connect with the same enemy in practice so long as the skill becomes burst-fire, so the skill's estimated DPS etc. are outright wrong.
