In The Secret World, there are many abilities which 'consume' stacks of a resource, but the descriptive text for these abilities is a bit vague in what effects are gained by consuming the resource.
Using the example of Assault Rifles, there is an ability called "Three Round Burst".
This is the descriptive text:
Consumes all Assault Rifle Resources. A single target Burst attack that hits 3 times, dealing 129 physical damage per hit.
As another example, here is the text from the "Shot of Anima" ability;
Consumes all Assault Rifle Resources. A single target heal that heals for 139 and gives a 3.4% leech effect to the defensive target for 5 seconds.
There are many other abilities like this in game, in these particular instances, would these abilities do more damage or gain any other effect from consuming five stacks of Assault Rifle resource instead of say, one stack?
The reason I ask is there are other abilities in game which specifically state that the number of stacks consumed will have an effect, for example the "Fire at Will" ability;
Consumes all Assault Rifle Resources. A TAoE Frenzy ability that deals 200 physical damage. An additional hit is performed for each Assault Rifle Resource consumed, dealing 63 physical damage per hit.
Is there a point in stacking the resource up to five before using the resource consuming ability in the instance where no benefit is mentioned?
