Is anyone else concerned about Jon Connington's battle plan, I mean it really feels as though they rushed their way into Westeros. Even with the Golden Company as allies, the realm in chaos, the Ironborn attacking the Reach, Dorne's plan to betray the Lannisters, and the Crown in disarray at King's Landing, I still, for some reason feel as though they didn't amass enough strength, manpower, and support needed to put Aegon on the throne. Am I the only who's feeling this?
