The video reward change is very welcome. It seems that the baseline reward is 5 crowns, and 10 pops up somewhat often, with the 25/50/75 still available at times. And they got rid of all the other junk options. I will miss getting the occasional decent troop card, but that is more than made up for by not getting any more recruits, tactics or blessings. Very nice change.
Also, the instant rebuild for a video is nice. I like that we can go straight to the retrain screen after a battle, and that it covers everything, including generals. That will really help out with war attacks, especially when you need or want to do both attacks in short order.
It is very easy to accidentally click when retraining one troop while medal dropping though. Force closing before the video was over prevented that from using up my daily retrain, but it wasn't my favorite set of extra steps.
