Urgot Q should apply onhit effects and his W should apply an MS steal instead of an MS slow
These + that Mana ratio for his shield being tested on PBE would make him actually worth picking again without making him insane
The MS steal to make him get more reward for landing his shots and autos and the onhits to allow him to effectively build lifesteal in some capacity.
Also, to clarify: effectively less slow since it would steal MS instead of straight up slowing.
10/14/18/22/26% MS steal instead of 20/25/30/35/40% MS slow.
The slow is only 1.5 seconds anyway. He would be stealing MS for 1.5 seconds
