The one broken thing about Pyke nobody discusses

Ummmm no he is not allowed he is forced. Also bty tank pyke was 100% stronger then pyke now. Lethality is not a plus it's a negative.

Duskblade has always been and will always be a problem until it is removed from the game.__

What pyke supporters say. "Cause you know... He is squishy so it's fair."

Nobody is a strong statement, a bit too far into hyperbole territory. However, the answer is no since there are no other AD assassin supports.

While him innately being an assassin is hard to deal with, DB does make it worse. I'd still say that the most frustrating thing with Pyke is his sustain. His W makes him very hard to deal with as you would normally deal with an assassin whether that be poke or CC Pyke can deal with both while still putting out midlaner level damage.

I would say though that Pyke is not nearly as broken as frustrating. Players feel cheated when they land everything and he E's away and W's for 80% of his HP back. While this is annoying a losing team can never rely on Pyke to get them back into it as he'll certainly die in an instant if he jumps in first, and never get a reset if the 4 cannot deal enough damage.
