Items
Hullbreaker is performing exceptionally well on too many users at the moment, which means it’s approaching dangerous territory. In this patch we’re looking to reduce its ability to stat-check opponents by reducing the amount of Armor and MR it gives, as this makes it too hard to stop a Hullbreaker split pusher in a 1v1.
