So I have a suggestion for the next update... This may sound dumb but hear me out.
Second base feature:
A feature for the next update is that you can have a second base using the same account.
I decided to talk this out in a larger detail so... You can transfer an amount of loot from your first base to your second. The amount you can transfer depends on town hall level.
For example:
Townhall 1: 1000 gold or elixir
Townhall 2: 2000 gold or elixir
Townhall 3: 5000 gold or elixir
Blablabla (Skip to town hall 10)
Townhall 10: 3,000,000 gold or elixir
In that case you can basically donate to yourself. This may sound overpowered but the amount of troops you can donate to your second base depends on clan castle level.
Benefits of this update:
People become more hooked on the game as they would want to max both bases.
Supercell earn double the money as people buy double the gems.
Since donating loot to another player is ruled out, I doubt this would pass. Your idea is the same as donating to another player, you just require linking the bases. That is why donating to another player is ruled out. People could create other bases and just use them to feed their main one. Not to mention, with your idea, if you don't want to play two bases you'd be at a serious disadvantage.
