Equipment always eventually became a standard expectation to get invited into groups no matter how expensive it is, REMA is a good example, so I'm worried it will be no different with ampulla.
That's not really a problem with the ampulla as much as the player attitude. If someone's asking for R25+ nyame to do an event or whatever other silly req, that still has a time/economic value. For the cost of one path C rostam (another silly shout req), you could buy the ampulla and repeat every ody v25 where it applies until you cleared it. You'd probably have gil leftover, too.
Of course the ampulla mechanic is a RMT's wet dream. It draws gil from the economy, gives infinite incentive to buy more gil and it doesn't affect the rate of how fast RMT can acquire more gil with bots or mercing.
It's not surprising at all that RMT find Hoxne Ampulla fantastic.
I know exactly zero people who are buying gil to fund their ampulla addiction. My impression is that it's mostly used by serious endgame players who are already getting 1.5mil a day from segment farms and people who are stuck on the ladder. Gearing one new job costs more than using the ampulla for months would.
Yes, gil sinks are good for RMT. It's possible the Ampulla ranks highly on them, but I suspect it's less than you think. The 1.1m npc mats that go into damn near every useful synth and many upgrades are probably 5x the sink ampulla is on a serverwide basis. It's still an extra sink, and I still like that. But, to be clear, gil sinks are also beneficial for most players.. do you want them to avoid things that help you because they also help RMT?
Put another way: if it didn't consume gil but was on the rarity of kraken club and cost nearly a billion gil would you still complain about it? It's a very powerful item that provides creep allowing players to complete content they would've failed damage checks on previously. You can get immediate access to it for only ~50m and use it for ages before you get anywhere near that price.
