I think players should be able to exchange their gems for shards. The conversion rate would be really high. I think this because a lot of players have pretty much all kits in every game mode and a ton of gems with nothing to use them on. I Personally i have 350k gems and i wish i could do something with them. I think this would work because you can make the conversion rate super high so it is only for players with gems they dont need but its expensive to convert.
