I applaud them for it. The spellmaking system was a complex method of giving people the ability to create spells which really wrecked the game. It made all other abilities moot. There was no reason not to use it, other than roleplay.
I see statements like this allot. They make me angry. You didn't have to use spells. The reason "not to use them", was that you didn't want to. It didn't make other abilities moot. It gave you the option of using either/or. It was BALANCE. Players could choose to use spells,or the skill, depending on how they conceived of their player-character.. "Overlapping" abilities were abilities that were balanced. Like security, or open lock spell. Open lock spell wasn't redundant. It let you play the spell caster concept to open boxes.
Stealth and Invisibility allowed you to avoid detection as either a mage, or a thief-type. It was a conceptual option. You could play it like mage. Removing "redunant" skills, removed choices we could make on how we conceived of our characters.
Removing the spell-making altogether, removed yet another way we could conceive of our characters. We no longer have to option of conceiving our player-character as a master of magic. A wizard-professor that makes his own spells. Or however you wanted to use the spell-maker. Removing it lessened the game.
