Promotional Series

Really want a reply. What is it with Promos?.. You go on winstreaks even when its broken the losing games you still fight hard and had a well rounded game. when everytime you reach to promos Promotional PROMOTIONAL series. you always get people who are MOST DEFINITELY playing out of their elo. Every time u get the "1 free win" promo game its always hard beyond comprehension because Mates suddenly become sub-par when you need them to pull through. Its probably a mind thing but damn. Is it some kind of algorithm to make u have to fight on edge 1-1 for your promos*[slayer-jinx-unamused]*
