I saw someone mention an issue with the right caster block and trouble getting that pin through. I had the same issue on the right one. I have to say I am a pretty loyal AE guy but so far things are not as smooth as the B6 assembly.
I hear what you're saying but in fairness, the B64 is an entirely new platform and 1st production run. The B6 was kind of like a B5M.1 and a much later manufacturing run.
