His early game = 2stronk. No honestly I have no problem with him the only issues i could see that should be fixed are.

-His jump no longer stuns
-his spear is a skill shot.

WORST PERSON TO LANE AGAINST HANDS DOWN

Edit: After looking at him more his scaling on his Q is too high 1.4,.

So Riot should nerf Pantheon because one person out of many millions cannot deal with him...

Except no one enjoys laning against him. His harass and kiting is too strong in lane.

he uses his ult to get away too often. but thats just something i hate. nothing you can do about that.

There are a lot of terrible people to lane against. These include but are not limited too:
Teemo
LeBlanc
Kassadin
Talon
Caitlyn
Alistar
Blitzcrank
Darius
Garen
Gangplank
Nasus(boring lane)
Fizz

Try malphite, laugh at him

This thing called armor and health, it's pretty OP

Some people throw spears. Mantheon only hits people with them, no matter whether they are in his hand when it lands true,

Panth is very strong early, cause he's pretty much useless late, unless you were reckless and fed him early, which is his mission.
