SadGhoster, I believe the main crux of Striking's argument is that MCreator teaches you to make things using MCreator. While that's all well and good, learning to make the mods using an IDE will teach you skills that can apply to other fields, like STEM majors in college, also known as "the only degrees worth getting." You are technically right in that a mod is anything that modifies the game in a way that isn't found in the base game, so even adding compressed cobble to vanilla Minecraft (and nothing more) would be considered, technically, a mod. You're talking about adding new, tiered ores and whatnot beyond diamond, and that's all well and good, but the big question you gotta ask yourself is: how is my mod going to be different from the dozens of other mods that add diamond+ tools? MCreator is limited in its functionality. If memory serves, you couldn't, for example, make a sword that inflicts poison when it hits something like the vyroxeres sword in Metallurgy. To do that, you need to crack open an IDE and actually work with the code itself. That is why Striking doesn't like it: you can't add much complexity.
That said, MCreator is a fair first step. For games like Minecraft, ones that don't have dedicated content creation tools, such things inevitably have...rather lacklustre first steps; it can be helped no more than one can help that the sun rises in the East and sets in the West. Hopefully, MCreator becomes a better, more refined tool for content creation; something that adds things even a neophyte can use, but that still has functionality that a seasoned veteran can find useful. Another criticism I've heard of MCreator is that the code it produces isn't particularly good quality, and bad code creates a lot more problems than good code. Still, its better than it not being available at all.
