-use lunge to harass by attacking a enemy hero then on a minion to get away
-burst of speed is good for running down enemy's, as well as for that needed attack speed against assassins or other AD-carry's
-Her ulti is good for saving her from death too, use as a last resort if they are on half health
-riposte works on all basics even the ones like ashes when she is using frost arrow, use in right timing however it works on minions and neutrals
-one last one, use her ulti when in team fights
-GL HF :D
p.s. problems
-please note that you will have problems with this build if faced with a heavy AP character
