BRIGHT IDEAS...Pls comment i am wrong
1) there should be some guild donation for resources which can be distributed by leader or used in wars
2) unmuting options
3) personnel messaging or what u call whispering in others morpgs
4)new resource conversion building
like 1:3 for gold.elixir vice versa.
5)prizes for every one in some new league of levelled players like 45-50 ..so on,where there should b rewards for most res gained,most trophies gained. (Every 4 days league)
rewards can be some new troops level specific, some tokens or else that can be exchanged in some buildings
6) finally events for festivals or important days in real.world
like boss killing etc.
