Second suggestions list.
1. Would be good to have "Finish battle fast" button - to instantly finish battle in 1 second (only if you will win) but it will use like "5 energy" instead of "1". Or maybe even better to make only 20 "fast battle finishes" for each player per day.
2. Finishing main quests for AP is also good idea. Or maybe for some gold ammount (exclude quests with gold to give away).
3. We need "Go to Skylancer forum" button somewhere on screen instead of just "Alaplaya Forum" button in prefences.
Also will be good to have "Submit Bug" and "Submit Ticket" buttons.
4. Daily bonuses would be good - like each day of week you receive some resources and upon last day - you receive one Gold Construction plan / a bit ap. The longer you play each day - the better your reward become, if you will not login in game for 1 day - your reward streak will "burn".
5. Jack pot - there how it works, each player can participate once each day in "Jack pot Wheel", you spin the weel and win random bonus. (resources, items of your lvl, cons plans etc) For AP you can buy more spins. MAybe make also some bonus spins for each lvl up.
6. Random event-quests maybe? Its still some sort of quests, but you will need id say like (just example) "20 players of 8-10 lvl to participate". And if 12+ of them succesfully win their battles - all of them receive event-quest reward.
7. Would be good to have some sort of "Arena competitions", lets say 64 players start, and only 3 will win prizes, but there should be lvl restrictions. And they must pvp each other without spending energy.
8. We have some sort of honour points, would be good to have "Honour shop" to spend those points for items with expiration period (like you can buy and use item for 2 days).
9. Chat expressions will be good (smiles), any of them.
10. We need ability to move chat window around screen, instead of just changing size. Also we need button to minimize chat, it sometimes hard to gather resources and speak in chat both at once.
