First off, notifications. I hate it when my troops are at full and I don't even realise it! So an easy simple notification would be nice saying that my troops are at full, rather than always glancing at the clock. Second, a new castle upgrade. For the stats, I don't really care about that, but it's the feature it'll unlock. Upgrading your castle will give you a bank of some sort and, yes, it'll have a small fee, but no as big as gaw or the others, because you've actually earned it, and the reason you have the bank system in a castle upgrade is because the only players that will really use it, is the big hitters with all those trillions sitting out, or wasting it on gold bars. Third, and I don't know if this is a 'good' idea but how about crews like GAW? I know May people will hate it, but it's actually useful, example for wars you can now see if your clan members are getting hit, and so players and meet other players! Sorry if any of these have already been mentioned, or already in the game
I don't like the bank idea. KaW is special because it doesn't have a bank like most ata games. Plus, osw would change with bank, and it would be a lot easier/safer. Need strip funds? Do b2b hte and bank.
