Look, in yonder days with games like FFXI, accountability was handled naturally. If a player sucked, they wouldn't gain XP as fast, they'd struggle to level, and if they were bad enough, groups would stop inviting them (or a BLM would Warp II them without warning). Because there wasn't a Duty Finder, because there was no cross-world partying, people had to be somewhat careful not make so many mistakes that word got around. The harshness of the game world and death penalties also imposed significant incentives for improvement.

In FFXIV, this doesn't happen. You don't need to worry at all about your reputation in any context outside of a Static; there's absolutely no challenge posed by the overworld or standard dungeons to force improvement; there are no real penalties for crappy solo play. The only incentive is getting forcibly removed from groups via kick-votes. That's what keeps tanks somewhat honest, and it's what keeps healers somewhat honest; do a bad job there, cleave the group repeatedly, let people die all the time, and you'll be removed from the party.

For damage dealers, on the other hand, there's no easy way to check this. Unless someone's paying attention via 3rd-party utilities, or is familiar enough with the job and paying attention enough to know the player's rotation is awful, bad damage dealers simply don't stand out enough, especially in larger groups.

That has to be fixed. Maybe it's not through a parse, per se; SE could introduce certain status icons that indicate how well someone's executing their standard combos, keeping their DoT spells up, and dodging AoE mechanics. Do a bad job, it turns red; do a good job, it's green; yellow for average. Maybe the solution is a parser. I don't know. But what I do know is that there has to be some mechanism introduced that alerts a party to poor damage dealers. That's not elitism - it's simply expecting people to do their job, and do it properly.
