and then i choose void staff or abyssal, zhongya, etc (ofc selling the rings)
i always initiate with Q+W or W+Q. I hit 2/3 times and then i use E to:
1- escape if someone else came or i know i cant kill the enemy
2- chase him if he tries to escape
i never use E to initiate, i use it to escape or chase
in early game i always atack Q+W and then i fall back with E
in teamfights..focus the AD/AP carrys , try to use ur ult on him, then W+Q , then fall back(E) and prepare for a 2nd target(in like 3/4 sec when ur Q is ready to use again), if u stay in the middle of the teamfight u will die in 2 seconds.
be carefull with silence, its my weakness, silence = no E = no escape
