Draven jungle sounds really fun actually, but id assume the early clears would be on the slower side.
His W resets on catching an axe, so your clear is actually pretty fast once you get your jungle item.
People is afraid of the unknown, and if something is not officially known as a meta pick it should not work. And they don't want to lose. Its silly but its how it works.
I immediately ran bot lane to countergank their nocturne and got a triple kill. At that point, it should've been clear that I wasn't trolling.
Because as far as most people are concerned, "Draven is ADC and playing him in any role is wrong and you're bad kill yourself".
If anything, they're confused and they've never seen it before. Everyone is afraid of the unknown, so they try to attack it until it becomes known.
That or the people you were playing with were 101% handicapped.
I'm going to say they were handicapped. I stole 3 drags and a baron and was legendary and my team decided that I was the reason we were losing, not the feeding sejuani mid or the flaming rumble top.
I play a lot of off-meta picks, especially in the jungle, and people seem to tilt/flame/rage so hard when you pick it, and the only time they ever will stop is if you get a penta. It doesn't matter how well you play, unless you get that penta. They'll rage as hard as they can and sit afk in base asking the other team to report you like our Rumble did.
