this is quite a funny build but here is a quick run down on why it is in like every challenger KR game right now.

• All early game runes got nerfed, comet and aery are basically only for laning now anyway. HOB is also extremely lane focused but you lose less scaling than before.

• Janna has a ton of on hit damage from her passive now, move speed is converted to on hit. This means she actually hurts quite a bit with autos that you can’t move away from during the w duration

• W max janna is able to roam super efficiently early game because she gets over 400 ms with just 300g boots with the right rune setup.

• Red tree is just better for janna, you go hob, cheap shot, eyeball/zombie and relentless hunter along with celerity and sorch.

This turns janna into a very very hard lane bully basically on the level of hob ashe in the early game. You use the priority from HOB to roam all around the map first, if anyone contests the priority just auto them to death lmao.
