i dont see why it is necessary to change shard shop conversion rate, since when you farm characters on hard node with double drops, you wont get more shards in total because your farming time will be halved. so no point of any other change because of double drop. by doubling shard shop exchange rate you are solving nothing, just creating more dissatisfaction and problems. CG should do once right by everyone and just add those double drops without any other change. that will help with farming of old characters and wont hurt anyone in any way.
