I don't think so.
The most damaging combos on lightweight were: xx, low On, H Fuujin->FB Rin, H Fuujin(->Hitoashitobi), P, On. So now its harder to end this combo with knockdown. (though it is possible to do 66, 5HS instead of second H Fuujin)
But I agree with TheSlyMoogle, it will be easier to do longer pressure. Special-cancellable 6HS with FRC before hit means it is easier to bait DP on opponent's wakeup.

Anji:
General Changes
all normals up until the end of their duration can always be gattling cancelled on hit or block
That means now Anji can start combos from random 3P without CH, RC or butterfly?
While watching these videos ( http://www.dustloop.com/forums/content.php?390-Guilty-Gear-Accent-Core-Plus-R!-Loketests-June-2-3! ) I noticed opponents does not recovery from Kou. So 60 untechable frames is enough to knockdown even if enemy is high in midair?
