I only downloaded the beta last night and played for a few hours. So far very enjoyable and the learning curve is flattened with the good tutorial. Over all quite impressed, and it's still a beta.
A few issues I discovered while playing (as Procipinee)
1. Spell book has a "String not found" as a title to the Slow spell
2. Champions with injuries - there is no context help when mousing over the icon to tell you how to fix it and I still don't know how to correct the issues.
3. City destroyed by a monster - all the resources that the city were founded on are also lost. This doesn't make sense. The resources should remain so the city can be re-founded.
4. My sovereign has Summon II trait, but it seems to have no effect on the level of the Shadow wolf that I can summon. It's still the same original level.
5. End of movement indicator needed - When I'm moving a number of units on the map, it would be good to be reminded in some fashion when they have reached their destination so you can do something else with them e.g. move again, build, whatever. Too often I have to keep checking their progress and click them to see how far they have left to travel and remember to get back to them in x turns.
