Yeah Cybergoth & Industrial skins are straight trash. The Cyberian one is nice (and it pairs really well with the gold gun), but nothing tops her weightlifter skins. So glad they re-introduced them this year. I didn't get them during last year's event.
Her Epic Skins are pretty nice, with Midnight coming to mind. I still rock her Violet Common Skin, which pairs nicely with Zarya's gold gun. But I agree, they can do so much with Zarya, but most of her Legendary skins blow. Which is why I wish some of her HOTS skins were in Overwatch, Cyberdemon and Thunder Guard specifically. I don't care if they don't make any sense, I would use her Thunder Guard skin until I turn blue in the face.
With regards to BlizzCon: The current narrative is pointing towards a second Omnic Crisis, & I'm interested to see how the cast reacts/responds to it. Winston still needs to bring back Reinhardt and Torbjorn, provided they had responded to the Recall.
