I agree, regarding SK in my opinion should be maintained 0.5 - 0.5. I would like to know the opinion of those who want to change to 0.5 - 1 or 1 - 1. Since those who want that, have not specified why.
Come on!
the SK 0.5 - 0.5 is very weak on the defense issue, the class is an example of a tank (it should be) and with that it is not what is happening.
So I think an adjustment to 0.5 - 1 is best.
With this relatively low prop the tank is no longer tank, consequently other classes make better the role of it.
