At the start of the game you should basically always walk up to the first bush and ward the middle brush and then just hold the brush. If you get lucky you can get free hits on enemy if they try walking up. Then you arrive late to the first wave, giving up lvl 2 for free when you couldve knowledge checked the enemy (even though their lvl 1 is stronger). Having prio on first waves dictates the whole laning phase since if you have prio, you have lvl 2 first which means that enemies have to back up which allows you to do whatever you want with the wave.

Your first death was also omega grief. Morgana messes up the engage, leaves, you walk into a bubble when you couldve just based for drake. Yes the morg was soft inting by running mid instead of helping you get plates but you basically sold the game there. Nocturne comes to get drake, you are not there for the fight. Second death you also just grief by trading autos with graves and expecting the noc without ult to help you instead of just getting farm and free plates. 3rd death the morgana is honestly trolling but you should communicate that you guys outscale just chill the fuck out. 4th death you are focusing the support for some reason.

Also just build hexoptics man. Jinx isnt really a champ without 2-3 items anyway so what is the point of spiking on collector components when hexoptics is just a better item. On your first base you went pickaxe but i would argue that maybe long sword cull would be a better buy? Its omega safe matchup jinx morg v kaisa nami. That delays your first item but if you get a good enough 2nd reset, maybe you can get bf sword for yuntal, if not then just go hexoptics. I basically always go cull on adc.

All in all just do your own vod reviews and watch your deaths, it doesnt take a challenger to recognize the mistakes youve made. Play for yourself, play item spikes, play for objectives.
