Two games:
Game 1: decent game overall - people are smart, wait for shrines to charge...actually know what they're doing. ADC plays safely enough that I don't have to spam shrines, and can actually roam for my chimes with a solid window. MAD RESPECT from the jungler cause I always left one or two shrines in the red side of his jungle when I went to ward/chime up, well into the end of laning phase.
...we start getting hit with the 3v4 bot, and our Syndra mid literally runs through all of the shrines in the red jungle with full hp, runs in 1v4 after we get wiped, completely ints, and then blames me for not having any shrines in lane for her. (First of all, IM FREAKIN DED!) and the entire next 15 minutes is just the rest of us carrying this Syndra while she flames the absolute hell out of me. (There's always one bad egg...but overall, everyone but the binobo knew what Bard actually did, and that game was actually pretty smooth)
Game 2: Kai'Sa is grabbing literally every relic within 0.5s of me placing it for a tiny heal and INTING into Vayne/Blitzcrank repeatedly. And I mean inting...he literally didn't even need to land his hook to catch her, she would run into MELEE RANGE OF HIM to keep shooting at the Vayne (who was nowhere near dead) time after time...he'd use his E, Vayne would turn, and more often by the time he used his hook he either "stole" the kill, or grabbed a minion through her fresh corpse instead of actually hitting her. She's blaming me for everything, of course, even though she literally is collecting the relics at full health while returning to lane...so I just say "fuck it" and go place all my shrines in the jungle after she reaches 1/5 (the 1 kill was from a jungle gank, and she got it from creeps after she died) and she just goes absolutely ballistic. "QQ You never heal me! QQ You're not supporting me! QQ You don't even help me in fights!" (cant really help you when you're literally OFFERING YOURSELF to a Blitz/Vayne. >.>) So once she's officially 1/7, I just straight up say "Hey Ahri, we're diving mid", end up getting mid and jungle pretty fed, and even though we lost that game, I think at least 6 people reported that damned Kai'Sa... (breathes deeply)
Anyway, I think the biggest issue is that some people just straight up don't understand what Bard does. I'm including Bard players themselves - obviously, if you're always out of lane for chimes, your adc is going to have a bad time - but more to your point are the teammates that just non-chalantly run about expecting you to just be some god tier burst healer...you're not a damn Soraka, and they need to chill.
