I understand why people don't want voice tchat in Sport Mode and I totally agree (and I don't think it will happen as everything is completely oraganized already in this mode).
But honestly, I don't understand people that are against voice tchat in open lobby ! If you want to play in lobby with people you don't know, you HAVE TO communicate to organize stuff, so you have to use this ******* text tchat right now and it is really painfull and not effective at all. Lobbies right now are messy mainly because of that. Yesterday, I've opened a lobby "Nurburgring Touristenfahrten Confort Tires", a lot of good and respectful drivers joined the lobby but it was so hard to organize because you have to deal with :
-"Wait I had to quit to buy the same car as you, I come back !"
- Drivers that are already on the track and are not aware that the rest of us were ready to start and waiting for them...
- Warn drivers with bad behavior
- Or sometimes you just want to tchat with other car enthousiasts about what you are doing (in my case yesterday I was trying to reach a sub 9 minutes with a full stock Swift Sport on Confort Soft tires)
Even if it was fun, it was exhausting to manage the lobby with this text tchat, so after 40 minutes I quit.
You probably don't play in open lobbies, to say you don't want voice tchat. And seriously, if you don't want to hear others just disable it, like in GT6... But you will probably miss a lot of important data about what's happening...
