You're suggesting a ban on the red orb. But you haven't proposed a method to do so. There are two ways:
1. Via text files.
This option won't work, because on HeroesWorld the rules forbid modifying text files. I think the reasons are clear.
2. Via rules.
This option adds a junk relic, which is also bad.
In summary: It turns out the orb is seemingly not needed in the game (IMHO), but there's no way to ban it either. That's just how it is.
