New Exploration Idea

I came across a thread talking about a potential cave system being added, and it made me think of Boom Beach’s submarine reward system.

For those who haven’t played Boom Beach, it is an awesome game. But here is the description of their submarine system

Basically, the player pays gold for the submarine to go and bring back rewards. The submarine can take days at a time to return. This system works well in Boom Beach because it has many resources like (Gold, Wood, Stone, Iron, Power Crystals, and Gems).

If this idea was implemented in CoC, it would not add any new resources. First CoC would probably have to add a cave/dock to the map. The cave would be where the player would pay for someone to explore for rewards or a dock where a boat is sent off exploring for rewards.
It really doesn’t matter which system would be added because they both do the same thing.

Let’s go with the boat though. The player would pay gold for the boat to explore and bring back rewards like Gold, Elixir, Dark Elixir, and Gems (very rarely). The boat could be upgraded to explore further. Longer trips costs more gold but may bring better rewards.
Other players would notbe able to attack the boat either.

Negatives:
-This idea pretty muchcomes from Boom Beach, and I know the games are completely separate.
-This may require themap to be increased a little bit.

Positives:
-it adds something newand fun to the game without altering the main raiding/clan wars functions
-if a dock was added, it could potentially make room for Mastermind’s Daily Challenge system, but the challenges come from boats rather than the air balloons.

This is a rough idea. Tell me what you think, and obviously I need to add costs and chances of rewards.
