285 hours seems a bit low. You need to play more. I clocked over 2200 hours myself last I checked (early this summer). It's probably somewhere around 2500 now.
Only twelve days since June? Even if you just play on weekends there were over 45 days of possible play time between the end of June and now, so no, that's not really that much. Now we may disagree on whether that's a good thing or a bad thing...
I've been playing ESO since it launched on consoles, and it's really all I've been playing, though I was pretty indecisive about my characters which is why it doesn't show and why I don't have a v16.
