I'm not denying it but from what I've read and heard it's a bit more complicated than just a money issue. This is all going off of memory so forgive me if i'm wrong and I would love it if someone else could properly explain this but I'm pretty sure most of/if not all of graal as a whole is really outdated. An example of this is that the developer tools don't even run properly/at all on windows 10. As you can see Dusty is already working on level editor slowly.

It's kind of a catch 22. They need more developers but the developer tools barely even work and to update/remake those developer tools they need more developers.

But going back to the point at hand. Server upgrades would probably require a lot of things being redone which I don't think would even be possible right now so of course doing whatever it takes to minimize server latency right now would be important.
