I tested it a few times, but Abaddon is so low damage he can't afford it imho.

did you think about blink dagger? it behaves totally broken and it actually is

Someone like WK does so much damage they don't mind spending a slot on a blink

from what i remember i didn't struggle from lack of damage

but i played a core aba last time like a year ago

this hero gives me ptsd because of this game https://dotaclassic.ru/matches/1019924

maybe try out this build order. basilius>>>phase bootz>>>dominator>>>dismantle it into armlet+mom>>>blink radi/radi blink>>>manta
