With regards to online racing, lobbies are where it's at. So much more varied and creative. The GT3/GT4 meta car situation that is Sport Mode is so mindnumbingly boring and out of touch. The vocal minority (the "I only race online with BOP" crowd) is so tiring. They can scream from the top of their lungs about the latest GT3 cars all they want, but at the end of the day they are objectively the smallest part of the overall GT7 playerbase, and do NOT represent the majority of players or their views on just about anything Gran Turismo related. The majority of players aren't making their opinions known via social media at all. I imagine most don't feel comfortable putting themselves out there in such a way, especially with the angry vocal minority ready to beat them down over it (usually in the LEAST constructive way possible).
I've said it before, and I'll say it again... I wish PD had a slightly bigger team and were able to put out a sequel to GT Sport (for the vocal minority to enjoy) with an online focus with more fleshed out classes and features to support this focus. Leaving the mainline series for the rest who have very little interest in the online competitive space (85%+ of the total GT7 players). This would also make it possible for the mainline game to be playable offline. Seems like a win win for everyone involved, but then again... that is predicated on PD having a big enough team to be able to work on two different versions of the game (which they don't). So, it may be a bit pie-in-the-sky but it seems like a logical solution, nonetheless. As it stands, the online and single player modes end up being a somewhat watered down experience, trying to somehow cater to two wildly different camps. That's my .02 anyway.
