As much as I've been waiting for years for this visual upgrade, those traps are a massive nerf to Nidalee. Lord knows Nidalee is in a very tenuous spot as it is. But it WILL hurt her to have her traps be so clearly visible. With how big and glowy they are, even the brush won't be able to conceal them. Top Nid already scales poorly, so spending gold on wards will -hurt-. Mid nid has to wrangle every advantage she can as well.
Unless some QoL changes accompany this... (flash->pounce bugs fixed, a fix for when pounce cancels auto attacks as if you'd pressed 'S', spear speed, lvl 1 R, etc...) then this will hurt.
