Riot Games released Patch 13.9 on May 3, and alongside the balance changes, there were a couple of bug fixes included. While these tweaks are usually made to improve the intections between champions, this bug fix ended up having the opposite effect, killing one of Lee Sin’s key mechanics: the quick ward jump.
The developers fixed an intection where if Lee Sin cast his Safeguard (W) on something that died as he was ward jumping, it would place the ability on cooldown for its full dution with no dash or shield.
