Just because you don’t get a reply, does not mean Blizzard does not read them. Development doesn’t visit the Customer Support forums, and they are responsible for gameplay decisions. The Blues that are here in Customer Support are Support Forum Agents, and they have no involvement with the development, nor are liaisons for the development.
Any feedback that you post here, will go nowhere, because the correct team that does collect that feedback, doesn’t come here, which is the game development.
Also, if you’re expecting a reply, it is not guaranteed here
