Anyone got any numbers as to what they do they all do the same thing?

Numbers are in flux, as a new version is tested on Tribble.

IIRC, the current state on Tribble is that it deals about 70 % of the damage of High Yield Torpedo of the same rank, but targets 3-6-9 targets.

Yes... They all fire a spread of 5 or 6 torpedoes, in a radial pattern, doing what appears to be AoE damage, with each level doing increased damage.

However, there is no need to go into details about it, as it is being changed, to be more like "Torpedo - Scatter Volley"

Idd... Torpedo spread is like SCV (AoE) and is effective to remove npc/pet spam as well.

You fire a spread of torpedoes at each target in your arc, limited by your skill level in it.
TS1 fires at 3 targets, TS2 at 6 and TS3 at 9 targets.

I played around with Torpedo Spread I and II last night. The major difference is that the torpedoes follow targets now instead of being a stationary AE like before. The damage seems to be slightly less than a high yield of the same rank (I think I read ~85% and that seems about right).

I can see this being used in combination with charged particle burst quite effectively.

This.

TS is still "useless" to "meh" for most. But on a shield strip, it's pure win.
