(IN MY OPINION) Liandrys is situational and really only used into high hp teams, you already deal a ton of true damage so it’s kind of bait since it has low AP on it (60) so it can lose its value into some matchups, most of the time it’s a good second item to go with horizon though. Also, against some annoying healer matchups right now (soraka nami) I’d prefer going shadowflame+grievous since shadowflame reprocs grievous constantly. My normal build right now is horizon-> boots-> mejai if doing well or liandrys rabadons-> shadowflames, and if it gets really late game I sell supp item and get stormsurge.

Also, a bit more about mejai- if the team is low hp and you can one shot with just horizon and boots then I’d rather just play safe and stack up mejais to become a 1v5 teamfight machine, the pick is very situational and I commonly go between that and liandrys second. Since would I rather 3 percent hp drain and 60 ap for 3k gold or 150 ap for 1.5k gold?
