Why am i losing so many games

Your shyv isnt shitty lol. Don't listen to them. Shyvanna is not the type of champion you want to play in solo que. If you want to carry your team you have to play easy champions who perfom well. That's why Kog, Udyr, Pantheon, Ahri etc are up there. They're very straight forward champions with good kits and numbers. I'd suggest learning champions more like Poppy, Trundle, Quinn, Xin, etc. straight forward champions who are nearly unstoppable at what they do. Shyvanna can easily be stopped by just kiting alone, and the more skilled your opponents are, the harder time you will have damaging them. Again your Shyv is NOT bad at all. Just not a good champ in terms of trying to solo carry. If you qued with 5 people who knew your strength as Shyv, you would be more likely to carry the game because your team could set you up. You're good at Nidalee and she's a good champion to carry with. You just have to make sure you take your towers, drags, etc to get your team the most gold you can. The more team gold you have, the less likely they are to lose fights.

at first glance, and the fact i DO NOT KNOW YOU, it seems to me youre a shit shyv. upon looking at your ADC games, looks like you are a better squishy player than you are at tankers. im not trying to be an ass or anything, just trying to answer your question

You play a shitty shyv. Git gud, or stop playing her.

Please pick one of the games in particular ... just looking at the ranked games and it looks like nothing but shyv. On the shyv games you seem to follow one set build path regardless of the enemy team. you just build the same thing over and over. One game the Talon on enemy team fed as F yet no thorn mail no randuins etc. Then next game lux is strong on enemy team but no spirit visage no maw etc. You just keep going for dmg with hp from what I can tell and just always build dev to hydra. Granted steraks and deadmans are awesome I woudl say the static build is what is hurting you as the ramp up time to get to full build takes too long for it to be effective vs building in accordance to what you need to shut down.

As well in many of your games you are the most tanky of your team / the engager so you need to look at getting items to survive the burst / weather the storm > jumping in and being the killer. If you can weather the storm and get your team kills you should start to win more and then by final build get more bruiser with the dmg items. An example would be the game with Kah and ahri... you had nothing to really counter kah's burst and you only had MR from witts end vs the ahri ...I get that you went 14/3/10 in that game but the kills didn't give you anything as you still lost and I would guess that is due to the lanes collapsing and not being able to pressure and take objectives while you farmed sated and got your build.

Another thing I don't see any rune page that is helping you on CDR and you are not picking up CDR items so not sure what you are trying to accomplish by going dmg oriented yet not having the CDR to constantly keep W up and dish out the AA Q aa combo's constantly. If you are looking at being a dmg oriented shyv then you need your CDR....even not dmg oriented tanky shyvs get the cdr!

As well no need for flash pick up exhaust for early counter jungeling matchups! As shyv you should be invading early and taking everything you can and exhaust will let you win when you bump into the enemy jg!
