you still get good rewards on them so I "watch" them. i have more than 1 account so i would start an ad with one account and just battle with the other. no need to watch the ad.
legendary tokens for sure. also, I like that you can trade X amount of food for x amount of oil. it really helps the lower ages. i'm not liking the council cards. i actually don't bother getting them.
i agree with the poster that pointed out that some ads are just too long. i don't know about...
i'd like some clarification as well but 'donation cap' sounds like it's the number of units you can donate, not the alliance gate capacity. still, the 2nd level (legal contributions and legal costs) is worth upgrading as this will make your progress faster in the long run.
On Android, I would get a network connection error and get booted after using the parliament once.
Also, i'm not able to donate to my allies on both ios and android.
the crown cost resets but the food costs seems to keep going up from what i've experienced. i think each player can make 15 gold/food purchases per day before it turns to a crown cost.
