These are excellent changes. Can't wait to see the rest.
I think Shade was nerfed very appropriately. I did a few tests and it performs at about an Orca level now. It is still faster so I think it is slightly overtuned, but better that it is slightly overtuned than undertuned imo. It will not ALWAYS be correct to make one, it will not win the first missile blindly anymore, and the health changes and reload changes make it more punishable and less exploitable for zerging the base down. These are all great changes that make it a more situational unit that it should be.
I would have liked to have seen a Solomon base damage nerf. Hopefully, the next patch comes soon.
