My prediction is that kled is going to be a mid lane assassin...with similarities to Nidalee's play style where he pokes from a distance before closing the gap for the kill...I dont think hes going to be a bruiser because in the video he relies on speed agility and high damage....all the traits of an assassin and hes much to small to play with the big boys as a melee. Also i think he will be a mid laner because of the whole 'river patrol' them they keep hinting at which suggest his a mid laner that excels at roaming. From watching that video i can also make a good guess on what his kit will be like. It shows kled and his cute lizard buddy using a total of 4 abilities. Kled's mount has 2 abilities and kled himself has 2 abilities.
In the teaser we see Kled using a pistol to shoot from a range(Q) and a spear to execute(E). And we see kled's mount charge someone and rip their helmet off with his cute raptor feet(W) and we see a raptor foot print in a soldiers chest armor 1 inch deep in solid steel. This could only be made if the raptor generated huge momentum running at a very high speed before kicking him in the chest with his powerful raptor legs. This will be his ult(R).
Here's my guess on his kit.
Passive: After leaving a bush one of kleds abilities becomes empowered for a short amount of time.
Q: kled fires a pistol at an enemy champion doing dmg (his main poke ability) (110% ad scaling)
w: kled's raptor charges in a short straight line stunning his victim...applying armor shred...and empowering kleds execute. (70% ad scaling)
E: Kled executes his target....dealing a percentage of their missing hp. (Does more dmg if kled lands his w skill shot) (percentage hp dmg)
R: Kled's raptor charges over a long distance at raptor speed in a straight line...if he runs into an enemy champion he kicks them in the chest stunning them for 2 seconds as well as dealing massive damage based off the distance ran before impact. ( 150-350% ad scaling)
