Rakan and Xayah

So, I'm mastery 7 with Rakan, I get into a ranked game the other day... My ADC chooses Xayah once seeing that I'm going Rakan. I was iffy about that.. I don't see many really good Xayah players lately.. Right? Okay so we get in match... EVERYONE is 6+ mastery with their champ except this Xayah and I'm like "it's okay, I'm gonna trust they didn't try to troll in my ranked game." So the game goes on, this Xayah, runs into every skill shot Lucian threw.. So I say, "Hey Xayah, Lucian counters you, so lets play safe" she/he reply 's with "Got it Runs into tower when Lucian isn't even close to dead" I was so upset.... Like, just because your supp is going Rakan and you happen to have the Xayah skin, don't go into Ranked playing her unless you're good... Please... I don't need you to play Xayah to win lane, I promise you ADC mains... Unless it is a normal fun game, refrain from playing her if you dont know how... Like, ranked means so much for me... I was trying to climb and i just, can't when people only play her because i'm playing Rakan.. Does anyone agree with me? Play a champ you know in Ranked and leave the fun for norms?
