Who actually expects to ever complete a Mythic again?
I don't know about your server, but on my server Alexandrites are never in anyone's Bazaar and when they pop up every three months on one guy's mule it's ten for 30K each. Also, LSs aren't doing any of the events for equipment any more like ZNM mobs and Assaults and Einherjar and Nyzul and Salvage, and Emp. weapons are better in almost all ways. The very idea that Mythic weapons will ever be achieved outside of Mog Bonanza is laughable in light of the evidence.
If you didn't have 150 million gil back in 2008 when people were doing these events, a Mythic will never be yours. That is just the way the game stands.
Adding injury to insult, if you beat the impossible odds and actually could get an entire linkshell to do Salvage and funnel alexandrites to just you for six months so only you could get a Mythic, you are then expected to spend months and months of soloing Magian Trials to upgrade them.
I mean, if the developers are looking into spending any time on improving the mechanics of obtaining a Mythic, they should just make a vendor that sells alexandrites for 5K each. At least then someone might be able to convince a small group of friends to do the assaults, ZNMs, NMs, and other events (or at least be able to dual-box or three-box these requirements) and might have a chance of getting a Mythic before the servers shut down.
