Agreed. I'm just participating.
Earlier, there was a lot of indignation that IA may not be compatible with Legion. No doubt, other posters will voice the same opinion later on. From my POV, this reaction may be natural in a way. But it isn't very well thought out because there is no logical reason to assume Legion and IA should be compatible.
And if FFGreally does have limited distribution rights for IA because of a licensing dispute with Hasbro then there is a end-of, full-stop argument against compatibility.
