Shopper without afr is like sex witout a girl.
dont think thats true, but I also voted for AFR, simply because in most cases you can do more damage without attacking from rope more easily.
As an example I think of weapons like bazooka, or missilie/pigeon at some narrow hide, where you often can do max. damage with attacking form the ground, but from the rope it requires much more skill. Because its a common belief that Shopper is mostly a luck scheme there should be a many skill components as possible in this scheme.
(btw: OT: this reminds me, that I totally dislike the TUS Scheme as it is; the old FB scheme or the WO scheme [from the tourneys that FFie hosted] are much better imo).
