Ah, so you mean you thought Matchmaking was an A-spec feature rather than the B-spec racing? I'd always presumed that referred to B-Spec.
I'm still not sure of the usefulness of that function for A-spec, I'd rather choose a lobby myself, and that's hard enough as it is without waiting for a random one to load.
If you played GT5P you'd understand.
There was a half a dozen set rooms for the month. They had restrictions on cars eligible and tyres. For example, it could be the equivalent of 500pp @ Suzuka Full on Sports Hard. You could jump in the queue at any time, and depending on how busy it was you'd either be in a room straight away, or you might have to wait a few minutes. I'd usually jump in queue, go make a coffee and I'd be in.
You knew what you were getting, you knew the restrictions, you knew the track. It was not like finding a random open lobby, where you may or may not be able to find one that suits, and will in any case have a random track.
If you've played iRacing it's not dissimilar to the way the online in that is organised, except that instead of having fixed start times for races they just began whenever there were enough players in queue.
GT5P had a pretty restricted selection of cars and tracks, so I'd imagined GT5 full would have more than GT5P had and change more often. I don't think it'd be unreasonable to have maybe 12-20 selections and have maybe half of them rotate every two weeks. 12 is a lot to cover a wide range of PP classes and still have some left over for themed races (for example, 70's sports cars) or one make races.
The seasonal system shows that they can already do this, sort of. They just don't do it with online.
Frankly, online in GT5P was pretty popular even years after it's release. A lot of that was probably due to there not being a GT5 and the GT5P "career" being so short, but people enjoyed it enough to keep playing. It was a fairly robust and simple system, and really fit the bill as an idiot-proof way to just get playing online. Choose your race and go.
The open lobby system by contrast is far more complicated. It offers more freedom, but at the expense of more time invested, both in learning how to use it correctly and it simply takes longer to find a race each time you want to.
The open lobby system is important too, no online game should ship without something similar. But likewise I don't think any online game should ship without a simple "get me playing now" button for online.
In my view, it's just another example of PD trying to dictate how the game should be played instead of giving options. Some people want the freedom of playing however they like online, and they should have it. Some people want a fixed goal to shoot for, and they should have that too.
