Getting slowed by Rylias does not make it op
Getting PERMANENTLY slowed by it from a champ that can constantly refresh the debuff before it wears off makes it OP.
As long as you cant re-apply the slow for at least 1 or 2 seconds after it wears off it won't be an issue. The point of the item is to apply a slow for 1.5 seconds or 1 seconds after landing an ability. NOT "apply a slow until you kill the enemy"
The only thing that needs to be done to the item to fix it is to make the item apply a debuff to you say say you cant be slowed by this item for "X" more seconds.
(similar to
not being able to knock up the same target for a specific time, or
not being able to dash through the same unit for a specific time.
i don't have an exact number but i am guessing 3-5 seconds after the slow starts its effect.
Also.. at least learn which skills have a built in slow on them in the first place.
telling me that
's slow is OP on
when she hit you with her W.. (which has a built in slow) just makes you sound stupid.
etc's slows are barely enough to kite or peel for themselves, even their cc isn't going to stop some 400 movement speed Darius/Garen from catching up to them. A cooldown of 1-2 seconds or only being applied by skillshots would be better.
E or her ulti, or somthing huge like
ulti
provides those same stats. it takes 10 min to reach that.. at which time my powerspike when i want those stats would be over.
and the extra 20 AP for 200 gold makes a huge difference for my champ.
