The cut in stars sucks of course, but was definitely warranted. You could easily get 12-14 kits for the winter canal for free on beta. With the changes (which are smaller than they appear, you drop from 1355 to 1160 free stars), you can still easily get the winter canal fully leveled.
The calendar on the other hand is even more impossible to get for free than it was on beta, that should definitely be ignored unless your plan is to spend a lot of diamonds. On beta I posted a simulation I made of the event which showed that 0.6% out of 100k playthroughs got enough keys with 1355 stars, so I imagine that's pretty much 0% with the nerf.
