It's all patience to be honest. I've been talking to multiple friends and their big concern is, guess it. Yes, the 30k Alexandrite. The only thing they see impeding them from making a mythic weapon is the amount of Alexandrite. True, it does seem like way too much, given their availability and high prices.
But how will adding Alex to Nyzul really affect making Mythic weapons? All I will see next is kids crying about how they've collected their 30k gems and now having to wait on daily restrictions of Assaults, Nyzul, Einherjar, Rank Up Missions, Possibly Salvage. These will most likely be Private First Class Clowns who only ranked up through repeating Nyzul.
I've been helping a group of LS mates complete assault missions to attain Captain, at the same time a buddy and I turn in our books for "Duties, Tasks, and Deeds." We've also been doing Einherjar twice a week. But if those wait restrictions are removed, Joe Nobody, who bought all his way through obtaining a Relic or lived inside Abyssea for a week or two to get his Empyrean. Blah.
Too much thinking is making my brains hurt. I just think it'll be an annoyance to see people breeze through Mythic weapons and I'm now starting to hope that the daily wait restrictions are left for the sake of preventing greedy players from obtaining a mythic in a matter of days and little to no effort.
