Good list, but I always have beef with people saying "it's not about the tool", because sometimes it kind of is about the tool.
True, a good designer should be able to make something awesome in any medium, but each new tool opens up new possibilities.
When I got C4D I could do things that I would have never even thought to imagine in AE.
Even C4D has it's limitations. What if I want to do crazy fluid sims? I might need a different tool.
Ha. At least you did name it.
I was working in an AE project and looking for a layer....I named it "moving thing"...at least I named it?
