It may not be necessary, however (mostly before the party update) when you're in pre-game and want to tell your team to pick a kit it can be usefull. But since the party update, and the /fmsg I wouldn't say it is needed anymore, and could stay as it is.Why is it such a big deal to talk before the game starts? Most of the time you have to wait like 20 seconds. It's not something necessary in my opinion.
