The issue here is finding a means to promote good standards of play that balances the wishes and styles of both sides of the community.

SSS was a bust in this regard, it's irrelevant to current content (I see it as an answer to Gordias, but I doubt we will see the likes that again, it'll be very interesting to see clear statistics between A4S and A12S) and there's no incentive to use it. Perhaps a better way of looking at this is to consider a way to take the toolkit SSS offers and apply it in a more useful and prominent way.

Perhaps a good compromise here would be to require a player to speak to the SSS npc to get parsed in their next instance? Stone, Sky, Sea, Satchel!

Incentives are a little trickier though, my immediate first thought would be to add achievements for hitting high numbers in various bits of content, but that would fail almost immediately at the first hurdle due to how more casual players will view that. A more balanced approach might be to throw it in the saucer and reward some MGP for getting a 'daily parse'.

I'll openly admit that something like this isn't going to make players better by itself, but then no one approach is ever going to achieve that alone, rather the idea here is to set the spark of interest that gets the ball rolling, thus hopefully getting a better percentage of the player base taking some interest and care in their performance in team content. Couple this with other angles such as content that showcases new abilities as you get them and the ARR trick of using 4 man dungeon bosses to demonstrate EX/Savage mechanics in a more forgiving form and I genuinely think it would be a good step forward towards bringing the player base closer together. They managed a great job of this with ARR's launch and I firmly believe Yoshida can do it again <3

Finally, the key here is finding a good compromise between both sides of the coin, flat out wishing that parsing was gone is as much of a disservice to the community as wanting to throw logs rankings on the front page of the lodestone. Having optional, discrete and non gated but reasonably incentivised content that can help players to improve can only a good thing in my eyes.
