Point by point counterargument:
You must realize that we know almost nothing about the game as of now.
Then why even bloody have this thread in the first place? My point is that without spellmaking they would have to make a stupidly large number of spells to make magic feel like, well, "magic."
The system of magical combat may be entirely different than what you are describing. What if each spell has a touch, ranged, and area effect option, and it does different levels of damage for each?
Then those are different spells.
How do you know how the damage for each spell will increase with each level?
It's irrelevant. If two spells deal different damage because they are at different levels,
then they are different spells and we're back to my original point: you may as well let the player decide how much magicka to spend. "Fire" and "FireA" (from Final Fantasy fame) are not unique spells, but they aren't the same spell. If you remove spellmaking and replace it with "Fire" and "FireA" you remove spellmaking but do not add unique spells... and if you make "Fire", "FireA", and "FireAGA" for each type of damage you can deal in Oblivion or Morrowind, then you're talking about making sixty touch-range single-target burst damage spells. Which ties back to my original point: you either have spell making or you have to make an inordinately large number of spells or you have to have a crappy magic system (see: Fable 2 and 3).
Each spell might not have a set power or damage. Maybe it levels up with you.
That would svck. So at first level I fight a rat and use 20 mana to deal 20 damage killing the rat. I face against the rat later, but I only have the spell option "Burn it with FIRE!" and so I have to spend 200 mana to deal 2000 damage, killing the rat? Yay, magic is now just a sword with particle effects.
Maybe the new perks you get will dictate new powers for each spell,
Making them, gasp, new spells and bringing me back to the original point.
perhaps, as you said, allowing you to combine certain spells and add time durations.
And this would be making new spells, or as some might call it, spellmaking :whistling:
Who knows? You need to take everything into account, especially because we know nothing.
The point of this thread is whether or not removing spell making is a good idea. My answer is "No, because you'd either have boring magic or have to make a number of premade spells that borders on ridiculous." I don't need to take into account anything you've "contributed" because your ideas are either, "Well, removing spellmaking could be ok because they may just have a huge number of premade spells" or "Well, removing spellmaking could be ok because they could just have you make new spells." One of those points has already been covered by me, and the other one is contradictory and stupid.
Oh, and your point on Oblivion? It's dumb, contrived, and stupid. Please don't claim you're using "logic" because you clearly do not understand how sales of a product relates to its quality. I'm waiting for you to claim to be some sort of business major because that would simply make me laugh.
