Thoughts on (Rumored) Shard Exchange

I'm not sure you understand what the term 'rumored' means. This sounds like you suggesting your ideas of a new system. That being said, I do agree that you should not get shards from chromium for characters you have maxed at 7* and there should be a system to remove these 'wasted' shards. However, i do not agree that you should be able to pick and choose your shards on a freeium game. If you could just trade in all the characters you don't want, for the few characters you feel are 'OP' or FOTM, they would not sell as many bundles or chromium packs. Playing to keep progressing your favorite characters is how they make money. If you could quickly (and freely/cheaply) get your desired characters, most people would get bored and stop playing as there is nothing to play for. Remember, CG is a business and they need to make money. Implementing ways for people to NOT spend money is just bad business. Packs are a gamble and are treated as such. Again, my opinion is that when buying packs, you should not get shards that you CANNOT use (which is different than DO NOT WANT to use).
