The dragon mythic path feels very tacked on in the last minute (which probably is what happened), both lacking in mechanics and story.
Telendevs claw is basically the only slightly hard thing to find for unlocking the paths. The only late game path even more easy to unlock is Legend because it represents a completely different branch in the story (see point 4). Swarm and devil have much more elaborate unlocking requirements which automatically makes them feel more special
Mechanically the Gold dragon is lacking.
The powers you get as a gold dragon are much weaker than what any other mythic path get. It is basically just a boost to stats and they come with a tradeoff in the form of losing armor and weapons.
And to add insult to injury there is even a spell out there which emulates large parts of the mythic path. Why pick this mythic path when you can simply cast Dragonform III? And when a Brown Fur Transmuter does that the spell is even stronger than the mythic path
The resistances are ok, but by that point of the game you can have protection from elements up 24/7. And you only get immunities at the very end of the game and because of what enemies you face you don’t need several of those immunities.
Oh, and the dragon form, which is supposed to be your true form now, can be dispelled, just as if its just a renamed Dragonkind spell, which it sadly is.
Gold Dragon lacks any signature or unique ability
As shown in Point 2, thanks to the Dragonkind line of spells changing into a dragon is not unique or special. The only other ability gold dragons get is the breath weapon which is both weak and hardly unique as Cone of Colds can do similar things and the Azata through Aivu gets also a breath weapon in addition to superpowers.
Any other mythic path gets something no one else has except the gold dragon
No impact on the story.
Late game paths were promised to have a large effect on the story. That certainly applies to the Swarm and to some degree on the Legend. But not to the Gold Dragon (and I think Devil). There is hardly any reactivity to you becoming a Gold Dragon apart from a few lines and certainly no huge effect on the story. The questline also is very detached with no real conclusion (and you can’t even use the pet you get in dragon form).
The Gold Dragon is also the only late game mythic path (maybe the devil too) which does not have a unique scene with Aivu when you switched from Azata, further showing how much effort went into this path as compared to Swarm or Legend.
The gold dragon is lacking both in the story and mechanically, probably because of being tacked on in the last minute, and needs to be expanded a lot or completely redone to become equal to other mythic paths.
