FC1 spawned the Pazuzu based punpun ascension,
fall of '06 on that one, shortly after was
tsuyo's upgrade on elephantjack's h.i.v.e. ,
pretty sure I started the MotAO 11 + abyssal recharge.
But Idk who started the discussion about what
kind of feat was affected by Embrace + Shun.
It definitely was On by mid '07 ... predating BG.
iirc the 504 feats build dates to around then
and that used the dcfs too.
