I find this thread rather ironic, considering the OP's posts in the spell creation thread. You are complaining about a game breaking lack of diversity, in this case one much more trivial (animation), while defending the removal of a feature in the other thread, one much more intensive to actual character development (spell creation).
Strange....
Although I agree, animations could use work. As with texturing, quest bugs, that dragon flying backwards over southern Skyrim....
There's actually more diversity in the current spell system than the previous one, even without spell making. They just failed to implement their improvements in the form and types of spells well. The durations, cost, values, and so on are way off, but the actual variety is better. Spell making would mostly only create variety in values, cost, duration - which would certainly be nice - but I think the improvements and additions of shapes and functions of spells was a major step forward. I'm not against spell making, I just like to point out that Skyrim's spell system is still superior to both previous game's spell system. I don't know what post you're talking about but it sounds like you misinterpreted or assumed to much.
