When will people learn that animating skills are far more improved by better animating programs...
no they aren't.
A program doesn't enhance your skills. A more advanced program can merely provide you with additional TOOLS to aid you with creating an animation, but these are meaningless unless the animator in question actually decides to take advantage of them, and even then they don't necessarily make an animation better. In fact, it's often the opposite, people lean to much on the special features of the program they use and mask the fact that they actually suck at animating, much like inexperienced guitar players tend to crank up the distortion on their amps to mask any flaws in their playing.
Lets look at a hypothetical situation. Lets say in flash they added a feature that automatically generated perfect particle explosions for you, and all you had to do was specify some parameters. They would look great, but is it really "improving the skills of the animator" or is it just a crux for them to lean on as opposed to actually learning to animate an explosion without fancy tools?
Sometimes animations made in pivot or easytoon are actually a lot cooler, because if they are really good, you can appreciate the fact that the animator in question was able to make an excellent piece of work with only their own skills, and incredibly simple tools at their disposal. It's often far more impressive to see a well done easytoon explosion, painstakingly done frame by frame with only black and white to work with, as opposed to a flash explosion full of blurs and gradients, taking advantage of multiple layers and whatnot.
To use my guitar analogy again, it's the same reason that you can really appreciate a great solo acoustic guitar player, because they don't have any effects on their instrument, or even a backing band to harmonize with. They're simply using their own skills with the instrument to create music that is just as enjoyable as a complex composition written for a full orchestra.
