Recently I picked up Talon, but I die far too often

Talon does have a pretty high skill floor, but compared to any other mid laners I can play, even lucian ap mid, I die about twice as often. His E is super easy to escape over walls after getting kills if used right, but what do I do in team fights? I usually wait for all the frontline cc to come out, flank the enemy team, jump over a wall assassinate adc, but I had to use ult to dodge support/backline cc, and then after leaving stealth I get destroyed every time. My team usually wins the team fight since I killed the adc, but is there anyway I could survive more often, and not trade kills? I'm willing to build a defensive item if need be because most of the time I overkill the adc anyway mid game, but what defensive items are a good go to for surviving team fights as Talon? I've tried split pushing instead of team fighting, and I do get a couple towers, but I lose more games if I am not in every fight, especially dragon fights mid game.
