I don't think the new Scott is useless but it really should get at least a small cost decrease. Nerfing it's range by 10 makes getting more than 1 pretty risky and micro intensive, so I don't think there's any reason it should still have it's old price
It is because it fails to achieve anything useful on a game. People have to stop thinking balance in a vacuum and spreadsheet stats and start asking themselves where do you put the scott on your roaster on 1vs1 or teamgame?
Does the balance change make the unit more useful on 1vs1? no - result no one will ever use it anymore here.
Does the balance change keep the usefulness of the unit on teamgame? no because Priest or Calliope are 10 times better for their effectiveness/price and those are on par with other factions counterparts. At the moment with this patch the scott doesn't achieve anything relevant, it was suppose to be oppressive because that was its main function.
Now that it's gone, what do you build the scott for? That's a real question because in my opinion there is not a single situation where I would think "I need a scott". The balance team is just killing USF late game vs heavy support unit strategy, as per this patch USF will be 100% dependent on doctrine to counter it.
