I agree that the relic grind is terrible, I recently started my zodiac dungeon grind and I got lucky, got my 1st item on my 5th dungeon or so. After that I've done around 40 dungeons in a row now without any more items dropping and as a result I've pretty much stopped playing this game aside from fcob out of frustration.

Grind with a clear endpoint is one thing, I can handle that. Grinding the same set of dungeons that give literally no reward at all to my character over 40 times with absolutely no progress is another.
