Fair question. It is the ramifications that would entail for the suggestion of changing how players get to 50.
This would certainly provide the instant gratification for some, such as the OP, and perhaps others, but disregard the rest of the player base that relies on the interactions with other players during each characters 1-50 journey. And yes, players can exemplar down to do content - but they would need a supportive game economy to supply them with the level requisite enhancements to do so. That is why it is an entirely game-changing suggestion. While it sounds easy to implement (just make the bird do it!), its ramifications would undoubtedly alter the rest of the experience for everyone else. Enjoy a well supplied market? That would change if this were to be implemented - supply would decrease, but demand would stay the same, if not increase as others have alluded to.
That being said, I will echo my original comment again that the Beta shard exists, and players who want to be level 50 in 2 seconds instead of 2 hours can go there to enjoy the game if they desire.
