i mainly play cm mode,and seeker for me is a weak hero but once in a blue moon i pick him,and he always need s to rush rad and win the game so making some builds like this is fun on some non cm modes where you can get heroes complitily out of position but in a team fight it wont do much you will just kill the suport same way you would by having rad or you will get angry of not killling the enemy carry after he scapes with low life
