Well, other than the fact that you changed that spell from a tiny minor single object image to a significant illusion of moving creatures that could affect combat, I didn't miss the point. The point is that you had to stretch the capabilities of the spell in order to get it to do anything in combat.
With Illusions, I still had tons more options in 3.5.
I stand by my statement:
"Before, one could use spells a LOT more creatively."
I disagree with your statement. There are very few spells you can use creatively in 3.x. You can be creative in which spell you use, but the spell itself is not creative.
Example of what I mean:
You have to get past a guard at a gate. In 3.x you can:
1) cast invisibilty and walk past the guy
2) cast fly and fly over the gate
3) cast sleep (or some other incapacitating spell) on the guard
4) use an illusion to distract the guard
5)etc
None of the above spells are creative: they all do one thing. But the PC is being creative to get past the guard by using a very specific spell.
But, that
is the problem with 3.x. You want to do X? Use spell Y; it does X.
Don't have a Y spell? Buy a scoll of Y.
There is no spell that does X? Spend some XP, some gold and some time and create a new spell Y which does X.
Magic is basically a "get out of jail free" card in 3.x. It doesn't matter what you want to do, if you are a caster then the answer is "magic".
It's like trying to explain something complicated to a small child: "It's magic!!"
Now, I like 3.x, don't get me wrong, and I loved playing a caster in 3.x. But, by the time you reach 10th level, combat in 3.x becomes vinilla itself.
Combat encounter in 3.x:
1st round: caster casts improved invisibilty on himself
2nd round: caster casts fly on himself
3rd+ rounds: caster flys over battlefield casting save or die spells and then damaging spells when he runs out of save or die.
Seriously, 90% of combat in 3.x above 10th level is simply that.
