Managed a game as her, went pretty well. Started off in the jungle until lv6,then just roamed to where the fights were. It's tricky with the ulti since its an amazing disable, but use it too early and you can't kill in time so don't get bonus damage. A lot of the time I was ending up using it to mop up, just to guarantee the win since we were usually doing well in the fights anyway.
you take W at lvl 1 then max passive and w in jungle. Take ult at 6.
Whether you get blink or shadow blade is situational, I prefer blink in most cases due to the fact it isn't countered by dust/sentry wards.
Pretty much spot on, been playing with builds over the weekend.
Second skill helps you stay up and kill faster, but your passive will keep you alive in the jungle as soon as you have two ranks in it. I've actually found laning till 2/3 is worthwhile.
Take the ulti at six, and then roam to gank as soon as an opportunity arises. Aim for the squishy supports >:3
It's pretty daft with her as a creep wave becomes a benefit to you as opposed to an impediment.
