ADC PSA: You ARE sometimes the problem, not the support! Be kind :)
I've been an ADC main for about 3 seasons now, and my roles get a REALLY bad reputation! Toxic, trash, flamer, selfish, cocky, greedy and just plain awful to deal with; there's a good reason for this reputation! Game after game i go in thinking "i don't feel like playing ADC" and then watch as the bot lane goes 0/6 in 6 minutes. The ADC is yelling at the support for not playing well, their yelling at the jungle and mid for no ganks and YET... it's NEVER their fault!!! Get this out of you mind! YOU are NOT perfect! You are sometimes a cause of what's going on, your over agro, you not picking good fights, your getting hit by skill shots, your shoving when you should be freezing, your not warding, there is number of thing that you yourself are doing wrong! I went into ADC BECAUSE of the support players out there! I enjoyed being able to have someone be there to watch my back in case of a mess up, i liked being that ADC who some what knew what they were doing. And just watching the ADCs out there flame the support again and again for no reason, just sucked to watch. If you think their that bad, you try laning yourself and let's see how that goes, your "trash support" can go support the top lane! I've made it my goal to brake the normal ADC trend of toxicity! I've never gotten reported for toxicity, i will get an honor for gg or tiltproof 90% of the time, and i've had SO many people add me for a duo. Instead of flaming the support who made a bad try, be more positive about that "good try!" or "We're a bit behind right now, counter engaging would be better right now :)" is much better than "HOLY SHIT WTF?!?!? WHY DID YOU GO IN DUMBASS!" or anything like that. If you're behind, play like it, don't rage at your team and take some blame!!! [slayer-jinx-catface]
TL;DR You're not perfect, stop raging at people and take of the blame!
