Literally nobody uses the in game matchmaking for savage raiding. If you suggest doing it to fill a slot, everyone will say no unless you're meming or something. It's worse than guided games in Destiny.
Look, having to use your phone or a laptop on an external website is a bad experience. Destiny should have an in-game LFG tool. The reason why in game LFG is a priority for an MMO and not really for Destiny is because in Destiny precisely one kind of activity really needs it - the raids - whereas in an FFXIV you need it for the majority of content; such a hunts; primals; and raids. Having said that, if you have a phone or laptop to hand then forming groups in Destiny is a far better experience and easier experience than in FF XIV.
The reason why Destiny is actually easier, is because in Destiny all your stats are public by default. In FF XIV you have to hope that the people you're recruiting use FFLogs. In fact, if you're trying to make progress as a solo raider most of the hardcore community who use the in-game LFG will exclude you unless you have either a clear (I never once saw anyone host a sherpa group for clear to help randoms clear, which happens all the time in Destiny) or a decent log at the fight you're progressing. So, to really participate in FFXIV endgame progression you have to run another utility and use an external website. Use of loggers is actually banned by the TOS too, just the devs turn a blind eye for personal use - they don't want you raging at strangers in matchmade dungeons because of their stats. If you're serious about progression in FF XIV and don't have a static, you still have to use an external website and also have to commit a technical TOS violation.
I really appreciate someone else with actual MMO experience chiming in, because I've raided in both WoW and XIV and feel like I'm taking crazy pills whenever someone suggests that they're great case studies for blind matchmaking working. (Although its generally the same guy, in every single Destiny thread, and not a widespread opinion).
The only instance where blind matchmaking works is with inherently easy content, or content that has been outgeared through stat inflation, both of which represent a case where mechanical complexity / team coordination can be effectively ignored and have no equivalency to Destiny's raids because of the lack of traditional stats and the focus on action platforming + intelligence sharing.
Also anyone who has been stuck waiting 40 minutes for an LFR raid, only to have a tank leave and get stuck waiting for another 20 minutes, only to have a guaranteed 5+ people undercontribute and/or not contribute while another 5+ don't interact with any of the encounter mechanics, and then wipe several times until you have enough stacks of vengeance to brute force the encounter,
knows that LFR is not a fun or pleasant experience (it's a joyless 40+ minute game of whack-a-mole, at the absolute best) meant as a cold hard cash grab for another month's sub fee from players looking for one more grind.
In-game LFG or bust.
