Thanks, I got the basics thanks to the various guides, also thanks to Adoede who just released a new guide.

My problem was of that (crucial) information not being presented in the game (or at least not being easily accessible). Not everyone visits the forums.

As for the conquest, it was a bit frustrating, getting a lot of trophies and arena tokens in the beginning, and now almost nothing from my runs.

Also it's still in beta, but it's not very balanced yet for all the levels. At around level 20 it's almost impossible to complete it on Normal, not to mention higher difficulty, even with the very best random allies you get. It should at least reward those who have the time and knowledge to find a good group, and to be possible to complete it at any level.
