Hi everyone! I'm very new to the subreddit but I just wanted to know someone's opinion on Jayce's itemization in game. I tend to rush Ghostblade, but for second item I rarely build Black Cleaver, but instead rush armor Pen if against tanks, or Iceborn gauntlet against AD assassins/divers. Boots of choice is usually the ones for whomever I'm facing (ad vs AP). I mainly play mages so I am not knowledgeable on lethality vs armor Pen, but is rushing Lord Dominiks regard second a bad move? I try to go a tankier but bursty Jayce with Electrocute and Ignite, since priority targets can easily be assassinated. I was also trying (as a troll build in normals) building liandries torment third item, since it would increase the same on Melee W as well as it's passive (7.5% max health against immobilized targets, which can be proced by Melee Q and Melee E.
TLDR: am I building a dumb build/ineffective Jayce with these alterations? I am finding success but I don't know if it's optimal.
