Geee, thanks for the sarcasm.
The dragon character itself was fine. Some dragons can be grumpy or nasty. Like any sentient being.
And no, a Dragon doesn't have to be in a castle. Though I don't mind if they are. The cave I found the hardest fight in the game (for my party that is) is a dingy, *bleep*y, small cave that a peasant bandit would think twice about setting up in.
For me, after ten attempts, I have given up. I am sure there are people on one of the hardcore modes who can do it one try. I'm not one of them. Since it's not effectively possible to flee I don't buy the "you can go away and come back" point. Reloading multiple times to simulate "leaving" doesn't help immersion/RPing.....
