i killed a BS solo mid twice today with death prophet by controlling the creep lane and making him pay everytime he tried to last hit, which i stopped about half of when he dared come near the creeps. You CAN kill a bloodseeker solo mid. Tinker is fantastic. If he comes near the creep wave to last hit, at the last moment laser him and auto attack him then deny the creep. never use missle, save mana for laser spam unless you have alot of mana/want a kill.
