Removal of +1 to BS Conduit was completely unwarranted. Conduit was a core item on several strong but not op builds. Spite Blademaster did not rely on third Blade Spirit, it just needed Conduit for defenses, third Blade Spirit was merely a little AOE bonus to it. I love that it could be used on Pierce builds and on Cold builds, I personally made two quite creative yet strong builds with it: Pierce caster Infiltrator and hybrid Chillwshisper Trickster. With this item removal I will have to rethink the builds from the get-go. I feel really sorry for the people that followed those guides and got their builds destroyed by one stupid nerf.
Removal of Aether rr from Corruption was also a brainless move, imo. Yes, Lightning builds deserved it (but then, it should’ve happened BEFORE all lightning nerfs), but Aether builds? A lot of Aether builds have only one -RR in mastery (some like Battle Mage got none), that nerf gonna hurt them a lot. And again, for no good reason.
