Verdict on the Rylais changes
So, I've been playing with the new Rylais on the live servers for a while now and I've got a mixed bag of emotions regarding the change.
Pros: -Cheaper, means it's easier to get even when behind -It's a lot less opressive due to the lower slow and AP being reduced -Makes fighting spammy mages not as unbearable (looking at you Cass')
Cons:
-The lower slow makes catching people a lot harder, especially with 325 base MS
-The stat reduction kinda hurts come mid and late game
-The build path is icky because you're left sitting on a 
Overall I feel the changes hit the mark, by tackling a lot of its problems like the high slow amount, the heavy AP that was slapped on top of the hp and generally making it less desirable on champs who do not really need the slow to function.
On the flipside it has become a lot harder to catch people with Mordekaiser since I no longer get the 40% Slow. If the enemy got tier 2 boots or some form of MS item/mobility you won't be able to force a fight and stick on them.
So yeah, overall more pros than cons but nothing a quick look at Morde can't fix. Overall a good way to tackle Rylais' issues while not screwing its intended users totally over.
