The community (as it’s GMod based) has a lot of people that have less powerful PC. Some of these people love the community so much they play on 10FPS the whole time and wish to talk to people while playing. Discord is not an option for them as it will destroy their already low FPS. TS is much more lightweight for people that just want to talk to friends while playing the servers. (Also so randoms can’t keep annoying you because of better permission controls on TS).
who even uses TS other than staff meetings and randon imp staff, TS isnt used anymore and only like 6 staff rooms are used
I love Discord and TS but each have their own benefits
