It's intended that channels like Miss Fortune's R - Bullet Time and Samira's R - Inferno Trigger break Duskblade's untargetability. Rather than triggering the effect only to immediately remove it, which would put the item on cooldown, we've decided to prevent it triggering altogether while channeling.

Champion power comes from both their inherent kit and the systems (runes, items, Summoner Spells, etc.) that players choose to opt into for that game. Ideally, the ratio of power that comes from those sources remains relatively consistent throughout the game. Early on, champions have a keystone and only low-level skills. As time goes on, items get completed, ultimates come online, and abilities get ranked up. But while attack damage and ability power ratios rarely change much with rank, items may each have ratios of their own. If these item ratios are too high, some champions start to become button-pressers for their item (looking at you Ezreal and Rengar) instead of standing out as their own champions. With that in mind, the goal of the changes to Essence Reaver and Stormrazor this patch are to limit the new attack damage ratios that champions gain over time while making sure they're a powerful source of damage early in the game. This change should make Essence Reaver stronger for most users across the majority of playtime but will be slightly weaker later.

Statikk Shiv has gained a few surprising users (hello, LeBlanc) and while we're excited to see players figure out cool new ways of using the item system, it's important that items don't produce poor gameplay when optimized. Shiv has an AP ratio in order to create an item that suits hybrid builds (Kai'Sa, Kayle, Varus, and Teemo as example users), but its best users ended up being mages with long-distance dashes who used it like a souped-up Lich Bane. Shiv is meant to be a strong source of wave clear that relies on champion input to finish killing minions. We're removing the AP ratio on minions to preserve that gameplay intent and the PVP AP ratio is being dropped a bit in order to make it not clearly better than items that already serve a PVP burst purpose. It's possible that LeBlanc and Zoe still enjoy Statikk Shiv with these changes, but the gameplay around those builds should be much fairer for their opponents.

Read Essence Reaver's context paragraph if you want to know why we're shifting power from AD ratios into base item power. Also, for those CTRL+F users who search for champion names: this is a Rengar nerf. Stormrazor has a ton of new users in midseason and some of that is because it was initially overpowered. It's actually just a touch weak right now but is also contributing to substantial late game burst. In this patch we'll be reshaping its power to be stronger early and weaker late, which should make buying Stormrazor feel like a strong power spike while still making marksmen rely on sustained damage for late-game success. Its Ability Power ratio is being removed because it's not a good mage item anyway and we're not willing to give them three Lich Banes so we don't want them getting any weird ideas.
