I do not beleive that these accolades actually have any affect. The kill 1000 of such and such species gives +2% all damage does not appear to have any affect, and certainly does not stack. I have a KDF tac with all of the ground kill accolades save klingon, orion, nausican and gorn. The damage output of his disruptor pulsewave and that of my fed, both with identical ground spec gear and traits(except for fed has efficient, KDF has elusive) not to mention most of them do not have Trophies. I was wondering if anyone else had noticed this.
