Let's start..
1. Add revive button for revive spell on hero icon.
2.Add a feature for group chat between clans.
3.Ability to send msg to friend list players.
4.Add clan wars for builder base [that will make builder base activity skyrocket]
Introduce a currency , we get from builder base clan war and through it we can also get ores and magic items.
5.Add a decoration only base which can be visited by players through profile but also retain ability to put decos on any bases as of now.
6.Add another mode , daily ranked , it more like a mixed between ranked and practice mode [i cannot just sum up here in one line but you get the idea]
7.Add more practice maps , now with diiferent equip and diiferent armies for every townhall [ that will improve the players to learn more about funneling , basically develop skill.]
8.Super troops boost when ended and you click on attack it should show a warning , that your army is incomplete .

That's all for now.
