As long as I have to pay a sometimes 50% premium to fly T+, they had better keep 100% status miles. Otherwise there is no reason in the world to fly or be loyal to AC. When it comes right down to it, it's just a seat on an airplane.

Do I care if my money stays in Canada or not-No.
Do other airlines offer lie flat seats on long haul- Yes
Are other airlines crews polite and competent-Yes
Can I status match with Flying Blue or One world-Yes more often than not.
Does Porter provide better service from YTZ to more places-Yes
Can I get AA miles on WS-Yes.

I think AC should not be looking at downgrading their elite programs but maintaining them at the very least. I can understand when they bring their program more in line with other star members, but to continue to water it down by a thousand cuts makes no sense. If someone is a straight orange member, and flies twice a year, I understand it from AC's point of view. But when you have to fly more than 25,000 miles a year, at a time when most travelers have no loyalty whatsoever, it makes no sense for AC to take benefits away from those that do.
