I recently completed the Hota campaigns and I would like to ask you; how hard do you think they were?
I tried beating all of them in 200% difficulty and I have to say that it was quite a torture. I had to restart the scenarios plenty times, trying to get the perfect result from every possible source in order to complete some of those.
In the end, I enjoyed them very much after managing to beat those challenging scenarios but it consumed a lot of time and made me nervous.
