It does 6% extra damage instead of 10% compared to pre-mythic Liandry’s, but it also loses double burn damage when a target has their movement impaired. It only gains 15AP despite these two nerfs.
Compared to new (post-mythic) Liandry’s it loses AH, mana, and extra % damage vs high HP targets.
Why is the new Liandry’s so much worse than both old versions, despite other items getting large buffs?
If it’s indeed too weak it should be adjusted later on, but I still think it’s quite effective now. Just not as flexible as mythic liandry
