I think TeamSpeak is dying. The v5 beta is awful. I know it's a beta, but it's so bad. It feels like they tried to create a Discord clone but failed greatly.
For months, I've been waiting for them to implement the Global Chat feature, and every time I ask, I'm just told that it's still being worked on but that it's almost done. I've been asking since the closed beta was released. Channel/Server settings are missing a lot of the basic features that TeamSpeak 3 has.
The design is so bad. Everything feels wrong about version 5.
I don't think TeamSpeak will survive much longer - and if it will, they'll manage the hosting themselves.
