It's been repurposed to an Attack Battleship & cruise missiles, which is the weapon of choice for Raven pilots, have received a significant buff to their performance. Overall the new Raven will perform far better than the old one.

Do you put effort in to being delusional or does it just happen?

I said nothing about PvE. The Raven is built to be an extreme long range Battleship, look at its bonuses. Like any ship in Eve, if you try to fit/use it in a way that does not favor its bonuses you will be disappointed. Yes, the Odyssey changes make it better at performing that role in a PvP fleet.

I think the real challenge with Caldari is that their two weapon systems, Missile and Hybrid (gunnery), do not share any skills. As a Caldari pilot you are forced to write off half of their fleet until you have good skill for missiles and gunnery. Other races have the same problems, both with weapsons and tank, so you can't really say its unfair.
