Mages are still abusing rylai's slow
Why gut the hp but not the ap? it doesn't make much sense.
Permaslowed forever
Easier to land stun
but people that needed it more 
feel so much weaker

We want Rylai’s to be purchased for its repeatable slow, not because it’s an optimal stat-stick. While that means toning its health and AP down to make it less generically appealing to mages, we also want the slow to be less attractive to mages who can’t reapply it consistently.
Cassiopeia, Brand and Malzahar are examples of champions who are meant to synergize with Rylai's Crystal Scepter.
The nerfs were never intended to stop them from buying it since they are the intended targets.
Kennen is another good example since while he applies it less consistently, he appreciates the bulk and ability to kite targets.
they made it 75 ap from 100 and lost 100 hp and made the slow passive different
100 AP -> 75 AP Maybe it's just my mage perspective, but that's a pretty big hit on the AP.
Do you know what "abuse" even means in gameplay terms?
They took 25% of the HP off and 25% of the AP. Your thread is dumb.
I feel like a good fix to the Rylai's problem would be to keep its old stats but remove the DOT proc. That is what makes every burn/poison/void-aids perma slow and become out of hand. It should only proc off of individual hits such as each stack of Taliyah's Q (who got hit hard by the rylai's nerf)
