NERF CDR ?! (sub 10.0.5)

Nerf of cdr (20sec to 15sec) as rogue sub when noone plays it or complain about it?The specialization is way below in terms of damage and one of the alternatives was to play CDR for did a control ATLEAST. This nerf is totaly no sense, why you dont nerf scalling of shadows on Secret technique i think its only that ppl want. You should play a bit at you’re game and not only in pve it will start to show.
