Please stop making Eureka

[Reynhart]

The existence of the welfare Tomestone weapon does not mean that, suddenly, the Relic wasn’t intended for the majority of players to participate in and achieve.

Ok, call me nitpicky, but nothing in the post you quoted says anything about "intended for the majority". It only says that the requirement will be "a long period of time" instead of difficulty, that for some people is also a hard gate. And, it may be assumption on my part but when he says "playing solo", I think he meant "without a dedicated group", since it's hardly reasonable to farm that many tomestones without doing any group duty.

Another point in that same post that I quoted for you is that the Relic also serves to give players a weapon that grows with them.

Maybe I'm reading it wrong but I can't find that part :s.

By shoving it into Eureka, it made Eureka aimed at them by default.

That's the problem, the official concept of Eureka does not match the concept of the old relics. So, people simply assumed that Eureka would be changed instead of the new relic being different, even if, between the Zodiac and the Anima, the purpose of the relic was already different.

And, as I’ve said many times, the Relic (and the other shinies) being in Eureka is the only reason people even touch the content, and that’s something I think the developers realized when they were creating the content.

You can't really say that. Assuming the relic wouldn't be there, they would have had to put another interesting rewards in it (Since, no interesting reward would kill any content), and we don't know what participation would have been on that situation.

Eureka doesn’t have anything deviating from any other forms of Relic grinds in past expansions though

Oh yes, it does. No tomestones required at all. And, for me personally, that's a huge selling point, especially since tomestones are already the main way of gearing making old relics basically more expensive tome weapons.
