1 Many objects disintegrates when I make animations. Sometimes parts runs away. Some parts just mysteriously disapears 2 The pivot point keeps running away. 3 Sometimes it take hours to delete an object. 4 Try to make an animation with an advanced object with lot of pivot points, try to turn it around a couple of times and it turns flat. 5 Try to drop an object with pivot points to the grown. I never know whats going to happen. 6 Resizing an object with pivot points don't work. Then try to turn it, and some of the objects keeps running into the oblivion. The torus is a real pain in the b***. It don't have enough options and I spend a lot of time with a calculator. And I'm no good at math.
