I know there are workarounds, it's just about figuring out if the workarounds will be ideal, or close enough to what we had before.
What GT Saturdays needs probably a little more than the Tuna hosted events, is the ability to have newcomers sign up without being friends with the participants. Having a host account, as you all know, is ideal for that situation.
That way, there is a larger pool of potential racers compared to just the 100 friends of the host-player -- not all of which would be interested in that one event. Instead, we get a full 100 players for any one event.
Though, maybe this feature was taken away because they have something even better in store for us? Like the ability to have a standing Event Room that exists as soon as someone from a list of participants opens it? That would be more ideal than the current Host-Account scenario, because it wouldn't necessarily be limited to just 100 people.
As with many things, it may depend on our feedback about the current features and how we hope the new features will work.
Let's play around with the possibilities and offer lots of feedback, just in case
