Idea global market, alliance market among the all, alliance members, global members

Need build a building bazaar"Global or alliance Market" .To trade in the global market, change,sell or buy heroes,troops, all ingredients etc. What you think?

It’s not an original idea and it already exists. The problem with that is that it basically means “unlimited loot” which will never happen.
You can’t get decent loot for winning titans and wars, etc. and you’re dreaming of that.
They don’t even want to make and Alchemy Lab that was proposed 1 year ago and has loads and loads of votes, though they said - please vote for us to consider this idea.
Meanwhile we get tons of new heroes introduced to the game we can’t ascend (1 hero out of almost 9 5* available for a color in almost a year)
