I have to say I'm pretty disappointed with the way mythic and ergon weapons were handled. Relic and Empyrean weapons got improved aftermaths, improved attributes, and got a much larger boost to their base damage. When it was originally announced Burtgang was shown to have 175 base damage, but as of the update it has 165. Excalibur's and Almace's base damage are actually 1 higher than the preview with the Dex on Almace going from 40 to 50.

I would like to see similar benefits for Mythic and Ergon weapons. Improved base damage similar to the amount Relic and Empyrean received, as well as improvements to their special qualities. Also Ergon weapons should get afterglow as well since they have to get 10k beitetsu as well.
