I'm all for Rylai's going back to a niche item....
But you're dropping the slot efficiency by 25% along with nerfing the main reason the 'niche' users bought it, which was the Slow+HP.
Total cost: 3200->2600.
HP: 400->300 ( 1067g->800g) AP: 100->75 (2175g->1631g) Slow: 20% for 1 second.
Yes, Rylai's desperately needed a nerf, but halving the slow in all instances along with removing 25% of its stats seems just a little heavy-handed.
Can't you try reverting it to its pre-pre-MYMU buffs and adjust it from there if it still proves problematic?
Total cost: 3000g->3200g
HP: 500
AP: 80 (likely needs to be 60-70 to account for MYMU AP drops)
Slow: 35%/15%/15% for Single/AoE/DoT spells for 1.5 seconds.
The item was perfectly fine back then.
If this version on the PBE rolls out, only the original niche users of the item will ever buy it, and they'll be gimped with it even though they practically require it to function.
The old Rylai's users will now have a toxic relationship with the item like old Vlad and WotA.
X Item will be held back because Y champions will abuse it if its decent; Z champion will be held back by X item because they require it to function.
Even Frozen Mallet didn't get hit this hard when it was must-buy on every melee in seasons one and two. And it got hit HARD.
Hell, even Ez was buying it for his Q spam.
passive on a more offensive oriented item and give to that item a defensive oriented passive) , and if champions end up being too strong hit their damage or ratios; gout completely Rylay damage is stupid
"I like these changes"
is already sitting at a 46% winrate, so I'd have to agree. They should honestly just revert the changes it received many, many patches ago.
