Elise is strong, but very underplayed

When I have to jung, I always pick Elise. I used to have a really good win ratio with her before I got into diamond (like 65%). I thought: "well I'm doing good for now with Elise because I didn't get to the hard part yet, I'll probably see later when it gets harder why people don't play her". Nope, Diamond 3 now and still doing really well and she remains my main jungler. My win rate did drop a bit (around 58% atm), but I still get complimented often for my performance and overall I'm doing great with her. I think most people don't build her right, this is my build (always, except when full ad): hp jung item, t1 boots, abyssal, randuin, magic pen boots, FH/locket depending on their team, last item either rylai if fed or thornmail/visage if need tankiness. Abyssal being the most important part of my build.
