well feather +12 for example is more OP than to this new acce to be released even at +18, but the difference is it gives more crit rate combined with +12% crit rate came from the up weapons, this combinations makes a 53/50 battle between feather user and to this new acce user since still you are both at 70% DD for example, damage wise and higher damages will be the key who will win in pvp between different acce users
