At the end of the day, SQueenix wants... needs as many people as possible playing FFXIV that could potentially enjoy themselves here within the style of game that it is. That means "good enough is good enough" will be true in many cases, and that bar will of course be lower than those that demand "skilled PUGs" for their randomized groups. If you want a group of like commitment to excellence, you can form it yourself. Meanwhile, approachability is king, and approachability can and will be "exploited" by those that "could do better" but... I mean why? Seriously, I'm one of those players, and I find FFXIV more automatically, gallingly "skill gated" in the SOLO MSQ! It asks me to play clases I'll never have any interest in and, yes, I make it past those checkpoints, but it's with disdain and "I shouldn't have had to do that," but I chalk it up to the impression I'm given time and again by threads like THIS VERY ONE: There are players that can only be part of the renowned welcome wagon of FFXIV only because the game is doing the gatekeeping for them.
Demanding a higher shelf for the core of the game will only lenghten queue times as people leave because the path of least resistance is gone, because SURPRISE: Many of us don't play games like this to "have resistance" to our fun.
There must always be an approachable path that, yes, leads to people being able to try your upper end content. If you don't want to group with the people that don't "belong in your group of excellence:" Form your own group. Me, I avoid the entire situation by leveling via DDs, Squads and Trusts, and from now on I will do all MSQ dungeons with trusts, and you will literally only see me in the ONE trial run I need when the story necessitates it... and I contend that there needs to be an NPC group option for that as well.
I will never join a savage group because they don't offer anything I need or want. My glamor is done basically forever, and power beyond what's needed for the next trust-enabled story dungeon is pointless to me as I play the game. That's my playstyle, and so long as it's supported, FFXIV will get money from me until they stop supporting me. Good enough is good enough, and I've reached good enough, and it's clearly not good enough for the performance obsessed... so be glad I have trusts and I'll see you for the trial carry!
