All they did was add pretty animations. Gow the hell can anyone mistake that for a better magic system. They gutted magic.
A lot of people seem to though. *points down*
Spell Creation added more to the game, that's a good laugh. The only thing it added was a different effect to a standard spell and a name, otherwise it looks just the same as any regular spell. Only reason people are complaining about it getting removed is for RP reasons and game balance comes before Role Playing any day of the week.
Far too many people desire form over function. I don't care if it's pretty; I care if it's a fun and engaging system. Spell creation was that and also a unique system that few other games had. Now we have a generic, but pretty, system just like all the other generic, but pretty, systems that most of the other games with magic have.
We can only hope that people wake up and smell the cutting before TES 6 becomes a pure action game devoid of RPG mechanics.
.....I have nightmares about this. I already consider Skyrim to be mainly action with some RPGs elements thrown in as opposed to Morrowind which was mainly an RPG with some action elements thrown in.
