Resource converter - hear me out!!!
I know I'll probably be executed on live television for even trying to suggest this, but since so many people have been, this is way that will benefit Supercell if they decided to do this.
Resource Converter - THESE FIGURES ARE SUBJECT TO CHANGE DEPENDING ON WHAT YOU THINK
Size: 4x4
Level 1
Cost: 750 gems (can be saved up but is hard)
Hitpoints: 1000
A level 1 resource converter converts 10% of gold/elixir into gold/elixir, 0.1% of gold/elixir into dark elixir, and 20% dark elixir into gold/elixir. A level one converter has a conversion limit of 500,000 of the original resource. You can top this up while converting. The conversion rate is 100 per second (so if you convert 10,000 elixir into gold, it will take 100 seconds to produce 1,000 gold.) While converting, 50% of any resource that is waiting to be converted can be raided, and 10% of what has already been converted.
Level 2
Cost: 1000 gems (can be saved up but is extremely hard, and it will force people to choose between 4th builder and converter)
Hitpoints: 1250
A level 2 resource converter converts 20% of gold/elixir into gold/elixir, 0.5% of gold/elixir into dark elixir, and 30% dark elixir into gold/elixir. A level two converter has a conversion limit of 1,000,000 of the original resource. You can top this up while converting. The conversion rate is 200 per second (so if you convert 10,000 elixir into gold, it will take 50 seconds to produce 1,000 gold.) While converting, 50% of any resource that is waiting to be converted can be raided, and 10% of what has already been converted.
Level 3
Cost: 1500 gems (can be saved up but is basically impossible)
Hitpoints: 1750
A level 3 resource converter converts 40% of gold/elixir into gold/elixir, 1% of gold/elixir into dark elixir, and 50% dark elixir into gold/elixir. A level three converter has a conversion limit of 2,000,000 of the original resource. You can top this up while converting. The conversion rate is 500 per second (so if you convert 10,000 elixir into gold, it will take 20 seconds to produce 1,000 gold.) While converting, 30% of any resource that is waiting to be converted can be raided, and 5% of what has already been converted.
Let me know what you think, and if any of the figures should be changed to be more reasonable. Remember, this way, Supercell have an incentive to put this into the game, as it will make more people spend more gems.
