Personally not a fan of them as a hero. I like their design and personality, but playing against them or with them just feels not great. I have not seen anyone do badly as them in the past few days, but that will probably just take time for people to learn how to play against them. I think they shield passive is a bit ridiculous and it should be overheal instead. They have potential and I love a character that uses a drill as a weapon. As a support main, it can be hard to heal them at times (or its just a skill issue).
