"Wins Lane" the champion

Why does this champion exist in his current state? He literally just wins lane. That is all he does. What kind of design is that? Miserable for his enemy early game with almost zero counterplay until high ELO. But absolutely worthless himself late game. That is such a poor design philosophy for a champion. It's miserable for both those playing as and against him. Playing against him you basically just stand around eating spears hoping late game comes eventually. Playing as him, late game no matter how much he destroyed his lane he is worthless. But it's not like you worked to destroy your lane because... that is literally just the design of the champion.

Sorry if this seems like a rage post. I use to enjoy playing Pantheon a lot. But at this point, he is just a miserable design. His entire design is point and click "Wins lane" and that is it. Beyond that he has no value.
