So, I've fought a couple of them now, and I would like to express my thoughts. I do have a couple of issues with them, but I'll mention the good stuff first.
First, they look AWESOME. Not just their appearance, but their PRESENCE. I was walking along a road and suddenly a gigantic shadow passed over me. I looked up and.... DRAGON. Holy old crap, that was intimidating. He passed over the crest of the hill and roared, and MAN was it a powerful moment.
Second, they are wonderfully varied in their tactics. They fight on the ground, throwing attacks in all directions. Biting to the front, sweeping the wings to the sides, tail to the rear. Fire breath and all that. They take to the air and strafe the ground, then perch and launch fireballs all over the place. It's dynamic, interesting and involving. However...
There are two main problems. First, they have that damage aura. This pretty much excludes all melee characters from the battle. I've seen this in other games, it's never a good idea.
The second problem is one that exists elsewhere in the game, and it's simply that the damage the Dragons are doing is far too extreme. Pretty well every attack is a oneshot attack, whether or not you're shielded, blocking or both. I'd LOVE to get stuck in, slashing and bashing, dodging the fire breath and occasionally getting knocked around by the wings or tail, but I CAN'T, because even the smallest of the Dragon's attacks will immediately oneshot me (or take me out in 3 seconds or less due to excessive DOT). It leaves me feeling disappointed and frustrated that I can't get in there and fight the Dragon and contribute something, however small.
I've seen this in other games, and even here in Group Dungeons. I've said it many times over 35 years of gaming, it's never a good idea to have your bad guys doing enough damage to wipe out the player characters, leaving them no way to defend themselves.
Now, I'm nowhere near the top of the line as far as damage output, but I'm fairly sturdy. My character has almost 30k health, which is fairly decent, and he uses heavy armour with all the relevant passives. I always build for durability. That said, I expect I'm closer to the top end of the average player, so if I'm finding Dragons pretty much unplayable, I have to think that a majority of players will ALSO be finding them so.
These are my main complaints with the Dragons (and some other bosses). I hope this criticism will be taken constructively.
