There was some screenshots of 2.4 of someone with 58,000+ GC seals. When it was spotted, it was assumed that it would be coming in 2.4. Obviously it didn't, but they are working on it. I agree that they'd need to clear up the 2.55 renegade story arc in the 3.0 MS, then maybe in 3.1 we can up the GC? There has been no statement of whether or not there will be a Ishgard GC either.
