Discord is puss? What? Sorry but i much prefer Discord way over teamspeak. In Discord you don't have to be in voice constantly while still being able to follow what's going on. If you've been away for a few days you can literally read back everything you missed, like in Skype group chat. With TS you can't be on different servers at the same time, keeping in touch with multiple communities easily. In general i think TS is also just shit to use compared to Discord.
Anyways, i highly doubt TS5 will bring that much that we don't already have on Discord. If it does, i might get it, but so far count me out lol.
