Fill player looking for 5s team

I can play any role. My default champions are nautilus, lee sin, and tristana as of late. I will generally take naut or lee in anything that isn't adc, but i have champs more specialized for each role. I have been stuck in B5 because my team mates are always toxic or someone DCs, where I try to do my best and can generally hold my own, but I am reliant on my team to do decently to if I can do anything in the mid to late game. I am very team oriented with my being unable to solo carry if my team mates perform very poorly (I'm talking handing my team the early game and them throwing it away). I am available for play on weekdays from 3:30 pm to 10 pm and am usually available sometime during the weekend on fridays and saturdays for late night (or all night) play and on sundays anywhere from when I wake up until 10 pm (cause I got school to worry about).
