It works well in other sims. The fault finding with it doesn't make much sense.
Also, it's not about space, but rather money. You can see with the amount of oeople who race right now, who currently have all DLCs, that space is not an issue, otherwise it would've been an issue before.
And good for you guys with money, but for many of us it's sometimes difficult spending money on 5 cars in a pack, knowing we'll never drive at least 3 of those.
If this doesn't make sense to you, this change is not meant for you.
