Since when was spell creation not user friendly? It was the same damn system as enchanting, and nobody complained about that. Nobody even said anything about having problems understanding SC until Todd spouted that spread-sheety BS. SC was not complicated in any ES. You could do some complicated stuff with it, but to use it to be effective with any magic style in previous games was not. Not really directed to anybody, but I had to say that.
I'm not saying it was complicated, I could use it without any problems. What I'm trying to say (Maybe I worded it wrong) is that it was necessary to add and tweak many effects to have a functional combat spell at higher-level Oblivion. High Fire Damage Magnitude wasn't enough (It would simple be a Mana-svcker), you need Weakness to Fire (Preferably in a hot-keyed separated spell) and Fire Damage at certain level to not be Mana-svcker and be Functional. You need a Shock and Ice set too, because of immunity.
With User-Friendly I was thinking if there was another way of presenting SpellCreation (Specially to new players) witouth dumbing it down and still having it to be a maneagable and customisable way of creating spells without the need of tweaks, weakness and more tweaks.
As a RP and Mage Support thing SpellCreation was amazing. But it was heavily needed if you wanted to do any good amount of damage at high-level Oblivion. A "problem" that could be simple resolved with more powerful Stock Spells. Still, I don't think that I explained myself right.
If we had more spells, spell making and spell combination (The thing that should happen when you Dual-Wield different spells) Skyrim's Magic System would Rock.
