Ok your very agitated with the change, I can relate because it was how I was with 5.0 changes, but you need to calm down a little, Sleeve Draw is not essential for an traditional pull timer opener, you will get divination out at the same time as usual because groups will work towards it, the extra cards only become essential for the opener when you get immediate pulls which do not tend to happen from extreme difficulty and up unless just going for mechanics which is where such a thing as getting Divination out on time starts to matter most.
The stuff lost is substantial, no arguments here on that, but there were other worse issues that 5.05-5.2 Sleeve Draw caused that enough people were complaining about that this change was made, it is a tolerable change to me because not getting Divination out on time because someone early pulled is far far less an issue than what I was having to deal with before.
Like to point to SB Ast on your last point, was busier than Whm, had more to manage, and was played way more. It is not just about simplicity, if a job plays like patooky to people they won't play it no matter how simple or how complex it is.
There will always be issues with Ast because they changed it so drastically in 5.0, They took away old problems rather than try to fix them but added new problems instead, they brought all this on themselves because they changed something a lot of people loved. Someone will have to bite the bullet, Sleeve Draw has been reworked twice since launch, and I think the least awful bullet we have had is not being able to get Divination out on time if someone early pulls. It is not a great bullet by any stretch but better than the worse one we have had until now.
So by all means complain but I will try to be just as vocal at keeping this version because I don't want that old bullet back(and just because the old bullet didn't affect you doesn't mean it wasn't still fired).
