[quote=@Host] Why? It's another resource. David [i]did[/i] make it from scratch. Tier Five never made it because there's literally no use case other than what he's using it for. [/quote] Because of the 17 years, at least 4 of them weren't usable for anything, and more likely 7 of them weren't. David has spent most of his life in his home dimension or at least on various earths. There's not really any dimension control resources possible from that, and if it's from the Scale buffer then it wouldn't really be able to alter dimensions because the Scale and Buffer don't have dimensions. I mean, it could possibly do so, but it's less than 50% that anyone would be able to come up with a good enough reason, even if we all worked together to think it up. Again, the only way it could work is directly manipulating Code somehow, likely very specific parts. Tier Five had/has a system to do that, but it wouldn't really lend itself to making a new one, sort of like trying to use Java to write a new programming language that isn't just a condensed/alternate Java. Saying that Tier Five couldn't use a defense system like that doesn't make any sense. A homebase or meeting place any number of other things would make it useful. Even if David were just like 2000 and had spent 1000 years of work alongside Myth and Z, I could kind of see that. He's brilliant enough to have a reasonable chance for that. But 10-13 years, most of which were in a dimension where time moved relatively slowly, meaning less work is possible relative to other dimensions, it just doesn't make any sense on paper, and I don't see any possible way to explain it. At least with Dark it's an Edison situation, find an infinite number of ways to do something incorrectly and a tenth as many ways to do what was intended, plus going around to countless other universes simultaneously to learn what other things knew/had recorded/etc. David's interacted with, what, 20 other geniuses? The input you've got just doesn't calculate to the output. Hell, even just getting broken into now and then using that to make it into what it currently is would make sense, but it just doesn't compute right now.
