Hail of Blades/Titanic Hydra tech
With the change to HoB to have less upfront AS but better AD scaling on the on hit true damage, I believe a nerf on paper ends up being a buff to J4 using HoB. J4 seems to like profane hydra more than titanic in the meta currently, but the benefit titanic has is that it's hydra active counts as an AA reset, whereas profane and ravenous do not. HoB adds a stack (up to 2) for any AA resets, and since J4 has high AS anyway with flag, you're able to pump out insane damage during the knockup with HOB empowered aa-titanic-aa-aa despite the AS nerf. The damage is comparable to a profane hydra burst combo, despite missing the lethality, and the benefit of having 600 HP early game makes J4 much more survivable. Late game, HoB is adding more damage to a burst combo than electrocute by a wide margin(about 240 true damage). Combined with sudden impact, a significant chunk of my overall damage output actually ends up being true damage which is impressive.
I've been running this playing lane J4 with very good success this patch: Rage5000#NA1 - Summoner stats - League of Legends
