I don't think there is any reasonable excuse that can be made for the situation they have got themselves in with customer support. But I'm sure they don't need this pointed out now when hindsight is such a wonderful thing!! All IMO of course.
But the bulk of your concerns comes down to your experience really. If you already know your way around, have most of your products already registered and working, then you need have no concern. I'm with almost everyone here, only calling support I think twice in the last 20 years or so, it was licence/registration issues, not support for the actual product. Everything I've needed to be taught, or shown the way, has been here, rightly or wrongly, or in the cake university, or just plain old google and Youtube.
I think your putting yourself through some misery for no reason. Just get it and enjoy it. I believe, like some others here, that this is the ONLY DAW that has progressed in the last several years.
Whatever you decide, just relax with your decision. Life's too short to worry about money, or support !!!
