I do agree that the old icon is obsolete and in my opinion rather ugly compared to the new one. I believe the new one should take its place. Also you guys should add the ability to link Discord accounts has become a relevant thing..
https://discordapp.com/It's an awesome app, with ability to create chat servers, customize rules and chat channels and what not. Voice chat and all that good stuff. You can create roles and administrators and take and give certain permissions.
