I don't understand...

Not playing up to par is definitely not subjective. If DPS aren't using core DPS skills, they're not playing up to par, if a healer keeps repeatedly letting the tank die and the tank is mitigating and it's only one batch of mobs, then the healer is not playing up to par. If a tank keeps dying from pulling too much, or if a healer is dying (provided they're not overhealing) because of enmity, then the tank isn't playing up to par.

You can't come to the conclusion that it was the action of a troll because I've come across MANY players just like that BLM that did not use core class skills and once I provided some advice, they actually took it and made an attempt to fix their rotation as the dungeon went on, which is very nice! Others have been very rude or just ignored me altogether. You can definitely go through 49 levels of content and not know a thing about your class if you don't read the skills, do FATEs, and only do the required story dungeons. Hell, getting to lv 50 means almost NOTHING because it is so easy to level up in this game compared to other MMOs, not to mention that classes don't feel "complete" until you get your lv 50 skills.

Play the game properly and use Party Finder. You can even set the pre-requisites to be as serious and "optimized" as you like instead of crying why everyone in Duty Finder(The most uncontrollable tool in the game.) can't be like you.

Why is DF not a "proper" way to play the game? There has been absolutely no one in this post that has forced someone to play like them. That right there is the argument made by people who think that putting in the least bit of effort is "optimizing".
