I thought Urgot's R slowed by 75%

Got that nice 0% slow :S

That's actually a great point!

Rito needs to follow their own philosophies:

False Choice -- Ineffective Choice Similar to above, except when you give what appears to be an interesting choice that is then completely unrewarding, or ineffective at the promised action. An older version of Swain's lazer bird had this failing... Because the slow was so large, you could never run away in time to de-leash and break the spell and reduce damage, and in cases you did, you'd just dodge 20% of the damage at a big cost of movement and DPS -- so running was just an ineffective choice.
