The 275 Alexander weapons have been in the game since 3.4. Back then, most "casuals" were locked into getting only the 260 relic or the base 260 Shire weapon after 7 weeks of farming A12. Those who successfully finished A12S could obtain a 275 weapon, and they were able to be top dogs for several months and have the other bonuses rewarded for beating Savage. But this is an online game and there needs be progression. The Alexander weapons are still the most powerful weapons in the game DMG-wise and they will continue to be until ~3.55. And then a few months later everything will go back to square one and we'll all be level jack at the start of Stormblood, and the process will begin anew.

If people want these misguided senses of superiority, they're gonna have to repeatedly earn it because the game needs to progress. I'm fine with people holding the strongest weapons in the game for doing the hardest content, but don't act like your momentary hard work is clearance to hold everyone else back for not submitting to the same idea of fun you cater to.
