Is Conflux a broken castle?

Interesting topic. In my opinion, it's just a regular Castle. Nothing special. Grail? Nonsense. I used to think it was great, but then I realized it wasn't. Just think about it. While you're building the Grail, your opponent will already have all the necessary spells. Next: growth. It's logical, because if there wasn't such growth, the Conflux would be immediately targeted due to its low hit points. So, I don't see anything "cheaty" about it.
