Is it really my fault? I wanna get better at not sucking.

Yes, a validation thread. But seriously. I gotta know. I thought I was doing things right but my team...all reported me? And a super salty maokai for reasons explained later- probably thought I was a hacker.

Ban stage goes normally. Team is silent, I try to be nice and chat but totally unresponsive. First pick Zyra, Second Wukong, Third Zed. We get to myself and final. Wukong was top not jung- so we had ADC and Jung open. Me being me and liking to do fun things, I was like "adc crittlesticks" and a Nami was instalocked below me. Total silence no one says anything, no one says "go jungle fiddle". I just think "weird, but whatever lets see it play out". Through a ton of the laning phase my support hit the cs and made me fall super far behind (11 to 39 at one point). She also dies a couple times in lane. I go "hey zyra, mind not tapping the cs". I take my money kinda seriously with odd picks. Ezreal was 1/0 and went to dive me with maokai- I silence him and fear (lcs style reaction imo, was pretty proud) and get Maokai to flee tower while Ezreal dies underneath. Rinse and repeat this the whole time until Zyra leaves to go mid, Ezreal dives me 2 or 3 more times. Same situation, fear under tower+silence+heal=free kill. At this point I have like... 54 I think it was and 3/2/0 kda so I was like "well lemme farm bot to try and catch up". Zed runs in and takes it all despite me pinging- I go top and take that farm. Meanwhile a farm breaks out mid, my bad for attention span won't lie. They all die but hey I got my full Infinity Edge and Bork (at 20 minutes ._.). Then the mid goes down when I finally finish recalling and team is complaining I wasn't in the teamfight. I try to explain my impact would have been minimal- I don't have enough adc items and I'm 2 levels behind so my spells are weak too. Doesn't matter- Zed calls me some lovely names to which I probably should not have responded, Zyra and Nami get snarky. All I can think is "it was a bad fight anyway you guys are super far down kda wise and Zed is doing pretty badly". Team still gets super mad and we lose towers and inhibs, me with minimal impact and complaining about cs every now and then. They all agree to report me. Maokai agrees to report me despite me never really using all chat (I think I said it once when Ezreal dived and he and I were both going "lol"). Anywho, how badly did I mess up?
