I don't mind the fate grinding at all. I'm really looking forward to some grinding content. I don't like the idea that you only need tomes to get gear. Every gear should be drops. It would make every dungeon more exciting. Now you just wanna finish it to get the stupid tomes and don't care about the loot at all (or well I like it for vanity but that's it)

I got my first relic weapon today, so gonna get +1 and then start the grinding and it's gonna be awesome!

I do agree with the echo buff part though. Getting help to beat challenging bosses just sucks. And it doesn't matter if I turn it off, everyone else will still have it!
I did titan for my first time today and we got him down to like 10% and then we wiped. One or two more tries and we'd have killed him, but since we had the echo buff it didn't feel rewarding at all to take him down
