Basically, to fill everyone in, I pushed it to the point of it probably getting quite irritating, but apparently made some very convincing arguments (the system of griffolyon and salamalyon being a simple 4-layer system, them being released later than zinrai/hayate/raiden, and the fact salamalyon was released independently). I also found a post from Brad (albeit before the rules were written) saying that the AR's should not be banned.
The committee are, as usual, quite busy, so there has not been a decision yet. Hopefully, there will be one soon. However, let's not get too pushy, I've probably worn Kei to the point of exhaustion over it.
As of now, apparently salamalyon is tournament legal as it got a non-hidden spirit release. It's useless, but hey, it's something.
Honestly, I don't think many people would have a problem with the AR's at least being used.
It was never a game-breaking/fairness issue though. Just a matter of tournament legality. Brad seemed to recall it may have been mimicking Takara/Hasbro's position at the time, which isn't great for the "legalisation camp" but yeah.
They'll announce it when a decision is made.
