Upgraded wolves are much stronger than regular ones, I agree. But for some reason, I didn't realize this until the third week. An upgrade to the third level? Interesting thought, although I almost never built the third level in this castle; I took other castles and stocked up on archers there.
Although there were other cases as well. Here, too, hidden units have an impact - if you have a couple of external orcs and a Jabarkas, it might turn out to be interesting.
And also, by the way, revival works well on upgraded wolves.
