unfair ff streaks costing you your rank?

i was in b3...and had a 10 game streak of ff's..didnt even get to finish any of them or even try..straight back to b5..how in the hell is that my fault?..how can that reflect my skills?..riot needs to consider revamp on Lp bonus for grade..even if it were just a losing team bonus..i dont think it would cause greedy behavior..but definitely would help elo hell's unfair toxic consequences..i can take a loss from lack of teamwork..but if i shine..it should show where it counts
