Lich + Bloodseeker = OP?

Have anyone ever try this combo? I think it must be great.

• Frost Blast : Nuke damage will always keep your enemy below half HP so BS will be fast almost all the time. Its slow allows BS to chase and eat his prey much easier from early to mid game. Combine with Blood Rite to ensure that your prey will be silenced.

• Ice Armor : According to his low HP, +9 armor to BS will grant him some muscles to deal with physical damage.

• Sacrifice : As Lich, this spell make him one of the best babysitter in the game. Your carry will farm much easier in the early game. Its ability to deny your enemies gold and EXP will put them in somewhat difficult spot.

• Chain Frost : This floating (slowly) ball will instantly spread the enemies out upon cast which means BS can chase and shut down the strayed.

** I've never try this before so this is only a hypothesis. Please try and tell me the result :)) **
