Is it unreasonable to seek people at the part of a fight as you are?

[Eidolon]

So, it's within 24 hours of patch 3.1's massive release. With this release, we see:

1 piece of high-end content (Thordon-EX)
2 pieces of middle-end content (Explorations + Void Ark)
2 peices of low-end content (Dungouns)

Today, I am frustrated by the high-end content. I create my own parties in PF, and lead them to the best of my ability. So far, it's going pretty well - I can get people to a point, but obviously, doing things like Thordon, there are going to be specific choke points.

The first one I've noticed is the Charge phases. Because of this, once I've mastered the charge phases (Whcih at this point I have. Only took about 2-3 tries, it's pretty easy!)

However, because of this progression, I attempt to create parties in the PF with the following tag:

"Thordan's Reign-EX : Mid Phase Party
Please be able to dodge charges. No completely news. Thanks!"
*For those unaware, this is about 3-4 minutes into the fight. The very first phase is EXTREMELY easy to learn but still takes a few tries to learn, especially the charges for most people.

Here are some of the responses I get because of this audacity to ask people to be at the same phase:

(I'm green in all of these)

So I kinda want to pose a question of the point of what that player and I were discussing - Is it wrong/unreasonable to seek people at the same part of a fight that you are? To party finder for those parts, specifically? I welcome thoughts/opinions.
