To answer my own question, I will simply say yes. From my limited experience this expansion, through guild and pug groups, it seems that the more people you add the easier a fight gets. And not always in the way one might expect.
As an example, I was in a blackrock pug, not many people in it, I think 11. The raid leader decided to add another healer being it seemed like we were short on heals, otherwise the fight we were on, iron maidens at the time, would go down, we just could not keep up at the end but DPS numbers were fine.
When in the listing asking for a healer a few damage dealers signed up that had high item levels. He figured he would grab them. This meant we needed to add even more healers. Soon this small group doubled in size.
Next attempt was a little better, but we added so many damage dealers we were back where it seemed we were before, we needed another healer. So we went to grab one and ended up grabbing three, two more damage dealers and one more healer. We had a full on party going here now.
The fight went down nice and easy. Lost a couple of people at the end but really it did not seem like the same fight it was with only 12 in the group. I would compare it to doing a 5 man dungeon on challenge mode (with 11 people) to doing a 5 man dungeon on normal mode (with 24 people). There was that much of a difference.
No more did we have the same person seemingly targeted by each and every ability. No more did people die to having too few heals on the platform when one healer left for the boat. No more did penetrating shot seem to take chunks out of people, it barely tickled them a little. Mechanics seems to be easier to handle, less damaging, and more manageable with more people. Not to mention losing 5 people to the boat means nothing when you have a massive bunch of people still on the ground among other things.
The people that were added were all good players doing solid numbers, don't get me wrong, but none of them were the savior of the group, that one healer to rule them all, that one damage dealer to blow everyone away. As a matter of fact all the original damage dealers were in the top, only two of the damage dealers added reached the numbers the people that were in the group at first pull had. The healers that were added, which is my opinion is what made the fight, were nothing super but enough to get the job done and keep most of us alive, none reached what I like to call pug god mode. Have to love when you get one of "those" healers. But they were all very solid healers.
So it is not like the group added a bunch of "better" players it just added a bunch of capable and knowledgeable players and that made the fight so much easier. There were no slackers, but there were not any before hand either. It was a pure number issue. The fight was easier all around because there were more people there.
This is just one, of many, experiences I have had while running with guild and in pugs that makes me believe that blizzard did not think of small groups or people that would prefer to run with small groups in mind when they made the flexible format. It almost seems as if you are penalized for wanting to keep the group small and it makes all the fights harder, sometimes, like on fights like this one, much harder with smaller numbers.
What do you think?
Have you experienced the same thing were many fights just seem easier with more people?
