Simplicity over complexity, time to change.

So what do you think would be the requirement in PF for people that wish to join T7 runs? I think you can answer than question yourself.

Quite frankly I don't give a rat's ass about PF. Everyone is, in fact, possible of building their own party. We see it all the time in the form of "Brayflox Sol Farm - NOT SR". I can't count the number of tears I've seen drop from players crying about not getting into parties. There is no rule or even vague notion that you are required to join someone elses party... Again, PF & DF are making this into an anti-social single player RPG. Here is a tip to prevent this: Socialize, make friends, find people who like to play the way you do as there are bound to be others, at least for now.

It is impossible to balance because the number of variables that developers have to balance with the multitude of gear out there is going to break the game in some form or another.

There is no reason that an MMO has to have perfect balance, none of them do anyhow. A little irregularity is really nice in creating inadvertent dynamics. FFXI was riddled with it, WoW is among the worst, Aion Clerics could solo almost any endgame dungeon. One thing that these all share in common? They were waaaay more fun in their prime time. The only thing that imbalance really hurts everyone in is PvP. I mean sure, it was disappointing that I couldn't get EXP parties as BLM in XI's ToAU but that lead the BLMs to creating epic manaburns or soloing mobs that would normally wipe an entire party of melee. My point is, there is no diversity at all in XIV and that is it's largest problem.

I remember raiding SSC in BC Wow and there was this boss called Hydross the Unstable. He was a water elemental whose attacks and abilities all dealt frost damage. If you had 0 frost resistance, which most tanks up to that point had none since content prior to that did not call for frost resist gear, you would be 2 shotted by his basic attack. So guilds had to farm for these gear from the trash leading up to the boss repeatedly hoping that the pattern for the gear drop and then had crafters craft a full set of frost resist gear for the tank. What you are asking for is basically this, again similar to my previous point, only one way and one way only to play the game.

First let me fix this for you.

only one way and one way only to play the single piece of content.

That's almost perfect, they added one encounter that you had to adapt for. It didn't stay stagnantly like this for the rest of the content, they added a layer of something and created depth. It means you had to work towards and prepare for one fight in order to defeat it. That is what I'd call adding depth, dimension and building an experience for your players. Because what do we have now? Go in, cross your fingers people know the fight and have low latency. If they don't, you lose, if they do you win? That's not a shallow experience at all...
