I don't understand why you ought to leave this forum. You can stay on it to talk about the Empire, and go on another forum when you want to discuss about AoS. I am a member of a french forum, but i came on this one because, even if it's in english (and i don't speak english fluently... hey, the guy on the back, i saw you laughing !), i am first an Empire player, so i can find more what i want here than on the warfo (french forum), which deals with all GW armies and universes.
For my own sake, i think a lot of people are not keen on AoS, because it is still seen as Warhammer's killer. I don't like AoS, not only because of that, but simply because i don't like what i read in its fluff, i don't like the sigmarines, i don't like the miniatures, there is no innovation for me, still the same gruesome communication policy, still the same staggering prices. GW didn't have to kill the Old World only to introduce bulky golden angels. That's what i think, but i won' tell it everytime i can, because it's useless. GW won't come back, GW doesn't care about what i think, about what customers think.
Wy don't you apply to be the AoS section moderator ? It could be resolve your issue.
I didn't know you, but if you think you must go, i tell you, in a good french :
Adieu et bonne continuation, Chevalier Noir !
