There is nothing to lead in any PF.
Creating a party doesn't mean you have to do call outs, answer questions, be ahead with mechanics, offer advice and corrections, provide macro or markers or anything of that sort. All it means is that you can set the requirements as you desire (ilvl, classes, other options, description) and have the option to kick someone if they don't perform according to the standards you set.
Many people creating a practice party in PF don't even have markers or a macro or any clue about what's going on. They just created the party, that's it. And nobody expects anything from them.
You just set it to "practice", uncheck "Duty Complete" and "Duty Complete (Weekly Reward Unclaimed)" as these two options prevent people without a clear from joining, add "helpers welcome" and "bring macro/ markers" if you don't have but want them and you're done.
Once you're confident with certain mechanics you add "from mechanic X onwards" next time you set up PF.
All these misconceptions you have come from a lack of experience but clinging to them won't help you. Why not believe people that are telling you otherwise from experience and be glad that it's not nearly as gloomy as you thought it to be and give it a go?
I created plenty of parties during my 1st tier in ShB, it's not complicated and nothing was expected from me because creating a party doesn't mean anything. And there are plenty of "7 other people" out there who perform the mechanics just fine.
And I agree with Kari that the difficulty curve from Hydaelyn (and Endsinger) Ex into p1s is really smooth. The biggest difference between those is that the dps check for p1s would be a bit tighter but this late into the tier almost everyone is at least 590 from augmented crafted and helpers are usually BiS. So not much to worry about on that front. There definitely IS a lessening of the difficulty throughout the tier, both through better gear and more helpers.
Right now you're the only one holding yourself back by stubbornly clinging to the belief that it's hopeless, that it's all pointless "bashing your head against a wall", unfair increase in difficulty and so on.
Not the game, not PF, not the difficulty, not the difficulty curve.
I get it, you're only after dyeable glam and seem upset that you have to tackle endgame raiding for it. But you are entirely capable of getting it. Yes, this late into the tier. In PF.
Is it worth it? That's your choice to make.
