Only time I've ever agreed with dotallyrad (this was written about a year ago).
Also you could isolate why you lost to a PL in the same way you isolated how you lost to Mirana: you (using you generally here, not "you" specifically) probably didn't gank one of the easiest hard carries to kill in the early game considering his only escape is completely countered by a 180g item that let's you kill him for free twice every minute, and allowed him to farm for 40 minutes until he became relevant and carried the game for his team. Or maybe you did try these things but you got hella denied by an OP KOTL that helped turtle for 40 minutes or a batrider that made it a pain to ever push with 5 teammates since he always scored a guaranteed kill on one.
People of course always tend to ignore the fotm "OP" early game heroes that allow the fotm "OP" carry heroes like PL to make it into the late game (with some notable exceptions like Earth Spirit 2400 range initiation), and only remember the fact that they got bulldozed by a six slotted hard carry... derp.
