No, if you take an outside perspective of it, it's pretty simple. Treat Hunters as Multi Boxers.
In Op's pictures, you'll see the hunters damage/kills gradually scale down based on their skill, All hunters will be near the top, just based on their ranged capabilities, however that doesn't mean they're good, or over powered.
As if you were fighting a multi-boxer, take out the hunter doing the most damage, from time to time the other ones back out after big-hoss gets downed. And the ones who don't back down are generically weaker back-peddling piss-poor excuses for players.
I would trade every bad hunter on my team for a good warlock any day. Point is, with the large influx of Hunters, and Hunter counters (rogues) they lack the quality and sensibility to be good players, and shouldn't be posted or complained about because they're 2-shotted.
