Kled hidden anti CC passive and Sick base HP

not sure if this was done on purpose.. or what... but whenever i get a hold of a kled and hit him with a Stun,snare, silence or suppress and he then loses his mount while he is supposed to still be locked down.. he all of a sudden just jumps out of the CC and is able to 9/10 times flash away... im sure this is meant but im just putting it out there that its kinda BS...

Also his base HP... i played last night vs a kled.. the ONLY item he had that gave him HP was Black cleaver.... +300 HP i think.. i was playing as a Leona.. so i had the standard tank and support items.. and had around 3200HP... kled on the other hand with mount and his own with just 1 item that gave some HP was pushing 3200-3300 HP.... did they not take that into account?? the mount on its own had 1900 HP on its own...
