I know that we have a separate feedback thread for relics, but I decided to create a new thread for one particular aspect of relics that puts off a number of players - the gambling style of acquiring relics through chests. Here is my suggestion @Fox :
I suspect that you don't want to offer relics for direct sale because of the way they can be levelled up as people would probably buy tons of cheap relics to level up their precious gold and diamond relics. Also, the sheer number would probably make it difficult too. So why not offer a single silver, gold and diamond relic for sale on a rotational basis (like cells in the cell shop) at a gem price that is based roughly on what you would get in various chests +20% as you actually buy what you want!
Still keep the chests as they are. Do this in addition to the chests and you will probably sell more as there are plenty of players that prefer a direct sale over a gamble!
