I dunno. I had a ST party once with a Drg who was using the unfinished Relic weapon as his weapon. Obviously he met or surpassed the minimum requirements needed to enter ST but I find that really annoying. His dps was terrible, as to be expected, and when I got onto him about it he switched his weapon out... with an even lower i40something weapon. I really don't think he was doing it to anger me or anyone else on purpose, because he eventually must have realized he lowered his damage even more with the even lesser weapon and ended up wearing the unfinished relic again to finish out ST.

I and the other members of the party practically carried him through ST. He died quite a few times, mostly because he just didn't have the HP to survive taking much damage. His gear in general was very lackluster, so to me that screams he's relatively a new level 50 player.

Personally, I don't like these kinds of players. It's not because they are newly level 50, but because they don't even seem to try to gear themselves up better for higher tier content before attempting to do that content. Sure you can enter ST at the minimum requirements, does that mean it's a good idea... not really. The dungeon drops i100 gear, please have at least an ilvl of somewhere between 80-90 before queing in. You'll be better prepared to survive, and you'll be a competent member of your party, assuming you even know how to play your job properly.

Back when I hit 50 for the first time, I sure as hell didn't start doing the relic quest until I had all of my Darklight armor and accessories. I wanted to be an asset to the other players I was fighting the primals with, not a hindrance so when I started doing Ifrit and Garuda I had most if of the DL set and what wasn't DL were AK/WP drops. So you can bet I ran Ifrit until I got my Ifrit weapon, and then Garuda until I got that weapon (at the time I think the Garuda and Titan weapons were the same ilvl so I didn't have to run Titan until I got that weapon). With my Garuda weapon and full DL (gradually replacing my DL accessories with myth accessories as I became able to do so [myth cap was low]) I felt quite confident that I wouldn't hinder whatever group I joined and secure in that I was doing the best I could do to work towards that goal of obtaining my relic weapon.

So yeah, it irks me when someone else doesn't even try, and it brings down the rest of the party/group's performance.

I'm not saying you need to be i100+ for ST, but at the very least be i80-90. That's not even hard to achieve these days. And for the love of god, if you're a dps, have like.. bare minimum at least an i70 weapon.
