On what bases should I trust your words? If GX merely wanted to get Robb out of the way, they shouldn't have attacked Perleone to try and take Ibladesh. I am sorry but GX didn't just focus on getting rid of Robb. They tried to expand and become a larger realm. Also, let's not forget GX's internal problems also spilled out. Kellen Dodger once was a member of GX then joined Perdan to see GX destroyed after GX went through some power struggles.
I don't know what was so unfair about dividing a realm that wanted to expand into two. GX would still have done fine even after being split in half. Also, when a realm becomes ridiculously large in noble count, people do tend to be afraid.
