It's not the only content though. Also at no point throughout my entire Animus section did I ever wait even 4 hours for a FATE. I know some have that issue, but that's why you target FATEs are priority and do other things in those zones while you wait, overlapping your time. By your argument you shouldn't bother doing any content until patch 2.55 hit because it's all literally now worthless at this point in time. Which is a poorly conceived argument at best. As someone already stated, plenty of people complained that the original leg was so boring and easy that many people just relic'd out with Zenith for all of their classes. And had it continued like that for up to Zeta that weapon who's stats YOU personally get to choose and cultivate would have been more powerful than the Raid Weapon for nowhere near the effort or patience.
How would that have been remotely fair to the others who were putting effort into their weapons or giving up weeks from their Poetics farming or working with crafters (or blowing millions on the MB for the proper materia).
The only reason you're having any issues at all is because as I pointed out, you're not tackling the grind correctly. You're not ensuring you're accomplishing multiple goals at once, and in essence are wasting a lot of time.
Now, on the remark about the grindy and rehashed content. ARR was never going to be h-amazing! it's goal was the pull a failing game out of the fire, dust it off and give it a chance. They had to play it somewhat safe. Now that it's successful I expect and hope that Heavensward brings us new ways to fight, explore, and cooperate with not only our FCs but with our community to surmount huge challenges. I love some of the ideas they've thrown out about exploration using Company Airships, and I'm hoping at least one leg of the next Relic journey allows for use of that system to help get whatever material is necessary at that stage (but don't make it required, that'd be bad). The Zodiac Relic weapon saga did one thing very right: It was a tour de force of the content of the game.
