What is the goal of a premade scenario group?

I imagine the goals are varied from farming PUGS, fun, to the challenge of meeting a similar group. A lot of the premade groups you will meet will be bomb spec’ed. Are these groups just in it for the farming or are they just using the most effective tactic to win? What would happen if scenarios as well as the blind queues, offered group/war band listings? So you could put your group up and accept challenges from other groups.

Would the premade groups still choose to just farm the PUG’s or would you get teams playing against each other.

But does this stray away from the point of ‘War’ which is the RvR campaign? The scenarios would still contribute to campaign but could they also add more? Then again would this kind of e-sport help ‘War’ gain subscribers, and if it did would it ultimately spoil the campaign shifting focus away from oRvR. You could then see this e-sport vocal minority calling for changes to classes to support the smaller scale team based combat.

I know there are more questions than answers. But that’s what scenarios do to me…

I always envision the premade group as the elite champions of your army, but shouldn't’ they be out on the field of battle and if they are not what’s keeping them in the scenario and off the open field?

Am I examining scenario’s too closely, are they just meant for the occasional distraction? Or to hide from the zerg when you don’t have the numbers and again I have more questions…
