So let me get this straight. Your argument is that the Infinity Minus One Sword is for the "hard core" players and should remain mind numbingly difficult to get, but that the Infinity Plus One Sword is for the "casual" players. Umm yeah good luck with that.

Untill Abyssea Dancing Edge and Shark Bite (and on high DEF mobs Mandalic Stab) were better than Evisceration and Mercy Stroke was the destroyer of worlds.
Take way the SA / TA and suddenly Evis looks much better then all of those except D.edge. And even then it was up to your camp and location.

Both of your arguments are flawed because your clinging to your relics and using them as some sort of social status icon. The item itself has no value, its a few bits inside your characters entry on the server. Should SE desire they could give every single player in the game a relic over Christmas and it wouldn't cost them a thing. The process through which you obtained your item is what has value not the item itself. SE making relics / mythics easier to obtain wouldn't hurt anyone or anything, it wouldn't cause your relic to suddenly rust and it wouldn't cause your d1ck to shrink. This argument has already been hashed out and the player base has overwhelmingly sided with the idea of making things easier to the causal player rather then harder. Truly "Hardcore" players make up less then 1% of a games population, most "Elite" players make up less then 5%. This leaves another 94% (give or take a few percentage points) of the player base, that 94% brings in more revenue then the 6%. This is how WoW has become so popular, it caters to the 94% not the 5% and definitely not the 1%. There are things that those "elites" can do, but nothing is preventing a casual player from doing these things, it will only take longer. In FFXI terms this "penality" is measured in years not months. A casual player could finish an emperian weapons in six months, an Elite player could do it in two or three, and a "hardcore" can do it in a month or a few weeks. These are more reasonable timelines and it has shown with the surge of popularity of acquiring them.

Unless your goal is to reduce the number of total players in the game, and thus the profits of SE. Then by all means continue with the campaign of "hard core" only.
