Straight up disrespectful.
My Zyra last ranked match decided she wasn't going to talk at all or ever use her summoner spells and continuously fed throughout the game. I kindly asked the enemy team to report her at the end of the match right before they destroyed our Nexus and they all said they were going to honor her.
I asked our jg to gank after her 4th death (I was 2-1 and she was 0-4 at this point I believe) and he never did. I said, "please Fiddle, Zyra is feeding". Then our Lux decided that I was flaming and being toxic (even though this was the first time I said anything) so I muted her.
I mean what can I do besides report Zyra? The enemy team LOVED her since she offered her death up on a silver platter and my team was consistently arguing amongst themselves. Sigh it was my promo game and everything.
