Why do we only want a swordmage, and not a more open and universal arcane half caster class? No other class is nearly as restrictive in terms of flavor. If we don't want the 30+ classes of 4e, the classes need to be a lot broader in scope.Well, it's literally called "swordmage," and where are you getting "unarmored" from? I gave it both light & medium armor, and an INT bonus to AC.
It's not a 1/2 arcane caster if it doesn't have access to the arcane spell list. EK is a great subclass. It works just fine if you choose the right spells.
As for why not the wizard list: because the EK is proof it doesn't really work. If it did, this thread wouldn't exist. The EK is pigeonholed into a character with a ton of rp potential that you can't realize because the spells that would help you do so either don't exist or aren't on your spell list. You can be effective, but that's not the gap that needs to be filled.
The wizard list is built for wizards, who are back-line controllers and blasters who focus on intelligence and are supposed to avoid combat. Which is the opposite of what we want the class to do.
Plus not all arcane casters use the wizard list, which is why it's called "the wizard spell list' and not ;the arcane spell list.' Every class gets it's own list. Which is why paladins use the paladin list and not the cleric list. If paladins use the cleric list, they wouldn't get any smite spells, (or elemental weapon) which are key to paladins playing like paladins.
