http://orig13.deviantart.net/59f0/f/2014/305/f/a/wallpaper_hd___soraka___league_of_legends_by_aynoe-d84xfai.png okay so i started off as an ADC main because in the beginning i had only adc champions so today i had played support and as an adc main i thought the job was easy you heal the adc help them fight no prob right...wrong so today i go in this game as and i was supporting a and he/she was a meany i healed and healed whenever i got the chance i healed so much she never died and by lvl 6 she had 7 kills. so i accidently kill AND SHE/HE WENT OFF. i kill him one time and get 1 kill when she/he had 10 kills and she/he was like (i crap you not) "OMG SORAKA LEAVE YOU STOLE THAT KILL WHAT THE F-CK" keep in mind she had 10 kills i had 0 i was too busy farming keeping her alive. so i did what she/he wanted and i left and she/he got reckt hard. do you have any support horror stories
