Aren't we going to talk about the jungle item changes or the ranged nerf of frozen mallet?

Frozen mallet ranged slow is reduced from 30% to 15%.

Tracker's Knife, Skirmisher's Sabre and Stalker's Blade are all removed and replaced by the Pathfinder's Knife, which is roughly a mix of all of them (Sightstone active which refills at base and by killing monsters, smite is usable on champion, deals true damages, reveals them and steals their movement speed) along with a new mana regen passive (replacing the old one ofc) increasing as you have less mana, only in the jungle and the river.

I mean, these are pretty big changes but they are shadowed by the AP Item changes.
