When to draft Enigma?

I'm really confused as to why people get so confused about the nomenclature of junglers. If you are running a jungler, unless you are sacking the offlane to run it, then that jungler can always be considered as a 4 position for your laning set-up, be it an Ursa, a Chen, or a Nature's Prophet. What he transitions into being is irrelevent to that, because that's what he is. He's is the greedier of the two heroes not assigned farm priority in a given lane to start with.

Like, it's just a number. It doesn't say a lot about how the hero actually plays in game, it's just a number relative to his initial farm priority, and arguably subsequent farm priority (That's not always the case, because farm priority changes over the course as a game anyway, so it's only a hard and fast rule in lane).

Also like the other two, I have no idea what analogy you were going for with jungle Sven. L
