I don't understand why Gaia finds reality marbles so threatening ?
Is it just me who thinks Gaia is overreacting a bit too much or have reality marble been nerfed.
I will point out my reasons below:-
1: they're too small to ever be a thread like at most a city block level from outside at least, and that's nothing compared to how big the earth actually is like that's a tiny dot like really tiny.
2: maybe if they grow bigger and stronger overtime I would understand but they don't do that either so I don't understand what's the problem.
3: the user doesn't stay in one place for a long time so it's not like it will be sitting in one place forever either.
4: a lot of the time the user of reality marble is either defending humanity or the planet so it's actually in her best interest to help them rather than crush the world.
5: maybe if Gaia was dying and reality marble users were able to replace her supreme reality marble with their own I would understand but even that doesn't happen.
I really don't see why she finds them so threatening because from the reasons above it sounds to me like they're harmless to her.
So my only conclusion is either FGO and nasu nerfed them or they were not that dangerous in the first place.
