Couple Ideas

Silver and Gold Chests: Would it be possible to use enchantment stones to open these, and or use less coins like make it 5 for Silver and 1o for Gold. I'm sure everyone complains about the coin issue and the costs to play this game. Also what do you think if we can sell the chest's in marketplace like we can with everything else.
Enchament Stones: Love the idea. What if we can sell these on marketplace, Or if we buy them buy coin let us get possibly 2 stones for one coin??
Uprgrading: I love this idea besides the costs

Sever Swtich: When is this going to be available.
Please let me know what you guys view are on these subject please
