That isn’t abuse, it is intended use of the game feature. If they don’t want players to do that, they can simply give a single chance, ask the players if they want to teleport back to the NPC after completing the quest, prevent them from moving or doing anything else, if players choose not to, the chance is gone. That’s how FFXIV does it, & that is intended use. In this case, you may or may not agree with the dev’s decision & design, but it’s still not abuse unless the dev themselves say it is. It’s not your call, bro.
Regarding to the @jordanburkex 's concern, it’s actually alot easier to make friends in this game, due to its grindy nature, you must party up with people & grind at certain spots, even for days. So it’s natural for you to stay in contact with several familiar faces who can give you grinding benefits (linker/healer/…) throughout your entire leveling process. When the mobs die out or the team sit down to recover, people start chatting about random things & know each other better. This was how people make friends in older MMOs, and Steam’s social system even adds much more to it.
