I'll pass it on, but I do need to comment some of them.

Units lost in battles stay longer in Infirmary. It is only 2 days now.

They stay there for 7 days, not 2. Getting more is highly unlikely, due to bi-weekly revival discounts (it'd be cool, though).

Personally, I'd like to see when each unit type will expire at the earliest.

Mobile App: Game can be played on Ipad or Mobile Phone. It is convinient.

While it technically doesn't exist, and won't for a long time (due to the game relying on Flash), you can use Puffin browser on all Android and iOS devices.

Interesting Events

"Interesting" is highly subjective. I'm sure that Plarium considers their latest addition to the tournaments, Brawls, to be very "interesting".
