The difficulty feels right to me. Bear in mind, this is the raid tier for 4.4 and 4.5. If people want to gear up, they don't even have to do so through the raid itself - they can do so purely through tomestones. There's no rush, after all. I prefer raid content to have a bit of a challenge to it, even on the normal mode. It's also why I like the Return to Ivalice raid. If people aren't paying attention, the fights are punishing.
